Which of the following are possible ways to eliminate a variable by multiplying first? x + 2y = 1
4x - 7y = 0

A. Multiply the first equation by 7 and the second equation by 2

B. Multiply the second equation by 4

C. Multiply the first equation by 4 and the second equation by 2

D. Multiply the first equation by 4

E. Multiply the first equation by 2 and the second equation by 7

F. Multiply the first equation by 7 and the second equation by 4

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.
