what is the solution of the system of equation?
you can also graph it and find the point of intersection

Combine all x in one side(right side) and the number in the left side. Example
X-9=3x+7
X-9-3x=7
Then resolve for x
(x-3x)-9=7
-2x-9=7
Then resolve for number and belong the x along
-2x-9+9=7+9
-2x=7+9
-2x = 16
Now you need to belon x along! For that you need to divide the number 2 in each side of the equation.
-2x/-2= 16/ -2
X= 16/-2
X= -8
