Question

How do you solve the following system of equations?: `3x – 2y = -7 , 4x+3y=8`?

Answer 1

`y=52/17 or 3.059`

Explanation:

Using substitution,

• Take any of the 1 of the 2 equations and isolate a variable (`x` or `y`)

I'm going to isolate `x` in the equation `3x-2y=-7`

That gives:

`x=(-7+2y)/3`

• Take that above and substitute it into the x of the other equation

`4((-7+2y)/3)+3y=8`

• Solve for `y`

`y=52/17 or 3.059`
