Question

Solve this system by substitution. y = 6x - 17 y = -4x + 3

Answer 1

x = 2 y = -5

Explanation:

Notice that both equations are equal to y

Substitute equation 2 into equation 1:

`-4x+3=6x-17`

Simplify:

`-10x=-20`

Divide both sides by -10:

`x=2`

Plug -2 into either equation to solve for y:

`y=6(2)-17=-5`
