Solving the system by elimination. 9x-6y=-12;-2x+3y=-4

Question

Algebra 361. Solution needed

Answer 1

Solve by elimination: 9x - 6y = -12; -2x + 3y = -4

Hello Dezi,

I am going to multiply the second equation by 2 to make the amount of y's the same

→ -4x + 6y = -8.

By adding this to the first equation, we get

5x = -20

→ x = -4.

Plug this back into either of the original equations to get y. I am going to use the second one

→ -2(-4) + 3y = -4

→ 8 +3y = -4

→ 3y = -12

→ y = -4.

So the solution is (-4, -4).

Thank you for submitting the question.
