Question

Solve the system of equations using the elimination method. Enter the answer as an ordered pair.

-x + y = -3 
3x + 2y = 9

hero · Answer

Hint: 

1. Multiply the first equation by 3
2. Add both equations together. 
3. Solve for y

anonymous · Answer

@Hero How Would I Set Up The Equations ? I Suck At This :((

hero · Answer

Alternatively, you can put both equations in the form y = mx + b, then set y = y

anonymous · Answer

@Hero so the first equation will be
-x+y=-3*3?

cunningham2000 · Answer

3(-x+y=3)    would be -3x + 3y = 9    Multiply each term by three

cunningham2000 · Answer

Sorry    -3x + 3y = -9     I dropped the negative

cunningham2000 · Answer

When you put the first equation over the second equation your x term will 'eliminate' or become zero.   then you can solve for y.

anonymous · Answer

@cunningham2000
-3x+3y=-9
3x+2y=9 
so it equals to x=0 right ?
