Question 150290: Show all your work
Solve the system of equations using the Addition method.
2a + 3b = -1
3a + 5b = -2

2a + 3b = -1
3a + 5b = -2
Multiply the first equation by -3/2
-3a+-9b/2=-1
3a+5b=-2
Add them
1/2b=-3
Multiply by 2
b=-6
Plug that in
3a+5(-6)=-2
3a-30=-2
3a=28
a=9 and 1/3
a=28/3
b=-6
