abe
Answer:
Step-by-step explanation:
2 times the first and –1 time the second will eliminate the x variables in the equations.
Option E is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
(1/3)x - (2/3)y = 7 ____(1)
(2/3)x + 3y = 11 _____(2)
Now,
Multiply 2 on equation (1).
Multiply - 1 on equation (2).
We get,
(2/3)x - (4/3)y = 14
-(2/3)x - 3y = -11
-(4/3)y - 3y = 14 - 11
Now x variable gets eliminated.
Thus,
2 times the first and –1 time the second will eliminate the x variables in the equations.
