Question

Solve using elimination. Show all of your work!

#1 -6x+5y=1 6x+4y=-10

#2 7x+2y=24 8x+2y=30

#3 9x-4y=11 x-3y=-9

*Please help! I'm really struggling, and can you explain the steps?

Answer 1

#1

Add the two equations to eliminate the x, then solve for y.

#2

Subtract the first equation from the second to eliminate the y then solve for x

#3

Multiply second equation by 9, then subtract from first equation to eliminate x, then solve for y
