Question

Solve this system of lineal equations.separate the x- and y- values with a comma 2x=68-12y and 8x=-28+12y

Answer 1

Explanation:

rewrite each equation

1) 2x+12y=68

2)8x-12y=-28

because the y values are the same number but opposite signs they will cancel out nicely.

10x=40

x=4

now lets plug x into any of the equations.

2(4)+12y=68

12y=60

y=5

(4,5)
