Question

Solve the following system of equations by using the elimination method.
     2x - 3y = -10 
     3x + 5y = 4

anonymous · Answer

Multiply 1st line by -3 and second line by 2. This causes the x's to cancel each other out.

anonymous · Answer

Therefore you can solve for y, once you know y, u can solve x using any of the two equations given.

anonymous · Answer

@ironictoaster can you do a step by step i get confused once i finish multiplying by -3 and 2

anonymous · Answer

Multiplying the 1st line out by -3
2x(-3)-3y(-3)=-10(-3)

-6x + 9y = 30

Multiplying the 2nd line out by by 2
3x(2) + 5y(2) = 4(2)
6x + 10y = 8

anonymous · Answer

New simultaneous equations are below. Notice if you add the x's together it gives zero. We add can add the y's together and solve for y. Once you got y, you sub in the answer into any of the two equations and solve for x

-6x + 9y = 30
6x + 10y = 8

anonymous · Answer

So you'll have 19y = 38 and y=2

anonymous · Answer

Sub in 2 for y in any equation and solve for x!
