Question

How do you solve the following system: #4x-5y= -1, 5x+2y=12 #?

Answer 1

Combine these two equations and get the solution.

Explanation:

When you multiply 2 (the first) and 5 (the second), you will get:
`8x-10y=-2`
`25x+10y=60`

Combine the above equations:
`8x+25x=58`
`x=58/33`

Put this value in the first equation
`((4*58)/(33))-5y=-1`
`-5y=(-33-232)/33`
`y=-265/165`
