Solve the system of equations by graphing.
{y=x-6
{y=3x-8

show work

You should subtract left sides and right sides in order to make y disappeared
and you will have the following:

y - y = (x - 6) - (3x - 8)    =>     0 = x - 6 - 3x - 8     =>     0 = -2x - 14    =>

2x = -14    =>    x = -14/2 = -7

Now you can use -7 in the system and you will get y
y = -7 - 6 = -13

So your answers will be:
x=-7 and y=-13
