Question

3. What should be done to these equations to solve the system of equations by elimination?

4x+ y = 15
3x - 2y = -8

A. Divide the second equation by 3.

B. Multiply the second equation by 2.

C. Multiply the first equation by 2.

D. Divide the first equation by 4.

Answer 1

B

Explanation:

If we multiply the 1st equation by 2

the y value of the 1st equation will get eliminated when added with the 2nd's.

and thus we'll be left with only X values and constants that are simple to deal with.
