Question

Solve the system by using elimination or elimination with multiplication.
3x + 4y = -2 and 2x - 3y = 10

Answer 1

3x + 4y = -2

2x - 3y = 10

---------------

See if you can get rid of one variable first. Lets start with y.

3(3x + 4y = -2)
4(2x - 3y = 10)
-----------------
9x + 12y = -6
8x - 12y = 40
-----------------
17x + 0y = 34

17x = 34
x = 34/17 = 2

now plug in this value for y and you will have your two variables.

Answer 2

Plugging in for y

take any of the two equations and use x=2 in place of x.

2x - 3y = 10 x=2

2(2) -3y = 10

4 - 3y = 10

-4 +4 -3y = 10 - 4

-3y = 6

y=??
