3. Given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solution. Show why this is true by solving the system of equations given. Justify the reason for each step. HINT: Use the addition property of equality and multiplication property of equality in your answers. (8 points: 1 point for each question)
5x + 2y = 7
3x – y = 2
To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)
Why is this multiplication allowed? (1 point)
What variable will be eliminated when the equations are combined after
the multiplication? (1 point)
Next, add the equations together. Your answer should be a single equation with one variable. (1 point)
Why can you add the equations? (1 point)
Solve the equation for x. (1 point)
Substitute x back into one of the equations to solve for y. (1 point)
What is the solution to the system of equations? (1 point)
Answer:
Step-by-step explanation:
To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)
5x + 2y = 7
6x –2y = 4
Why is this multiplication allowed? (1 point)
Because the entire equation was multiplied by the same number, the equation remains the same.
What variable will be eliminated when the equations are combined after the multiplication? (1 point)
The Y variable
Next, add the equations together. Your answer should be a single equation with one variable. (1 point)
11x = 11
Solve the equation for x. (1 point)
X = 1
What is the solution to the system of equations? (1 point)
X = 1 and Y = 1 so the answer is (1, 1)
(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)

55x + 10 = 230
What is x?
Answer:
x = 4
Step-by-step explanation:
55x + 10 = 230
=> 55x = 230 - 10
=> 55x = 220
=> x = 4
Therefore, x = 4.
Hoped this helped.
Answer:
x= 4
Step-by-step explanation:
solving equation step-by-step.
55x + 10 = 230
Subtract 10 from both sides.
55x + 10 − 10 = 230 − 10
55x = 220
Divide both sides by 55.
55x/55 = 220/55
x= 4
Our Answer: x= 4

Sally has 243.75 pieces of candy. John has 27.4 pieces of candy. How many pieces of candy do they have in all? John thinks altogether there are 217.15 pieces of candy. Is he correct? Explain your thinking.
Answer:
Yes, John is correct.
Step-by-step explanation:
To find the total amount of candy you must add the amounts Sally and John have. Sally has 243.75 and John has 27.4. When you add those two together you can 217.5 which is what John thinks therefore he is correct.

F(x) = 6 (1/8)^x is an example of
An exponential growth function
A logarithmic growth function
An exponential decay function
A logarithmic decay function
Answer:
Exponential decay. Your growth factor is 1/8, which is between 0 and 1. Thus, the value is decreasing exponentially.
If the growth factor is greater than 1, you have exponential growth. Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.
