Question

Multiply each equation by a constant that would help to eliminate the y terms.

2x-5y = -21

3x-3y = -18

What are the resulting equations?

6x-15y = -63

– 15x+15y = 90

6x-15y = 63

-15x+15y = 90

6x-15y=-63

– 15x+ 15y = -90

## Answers ( )

6x-15y=-63

-15x+15y=90

This is because you are multiplying the first equation by a constant of 3 and the second equation by 5 so that you can have -15y and +15y which will cancel each other out.
