Question

Solve the following system of equations.
6x+9y = -3
6x+5y = 9

Answer 1

to solve by elimination subtract the second from the first solve for y then use that value in the original to find x

Answer 2

ok so the simplest way to solve this equation is to use the process of elimination. So we subtract the second equation from the first so 6x-6x=0 and 9y-5y= 4y. -3-9=-12. So now we have 4y=-12. Do you know the next step?

Answer 3

divide both sides by 4?

Answer 4

x = 4
y= -3
