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

Try substituting the second equation in for y in the first, to get: x - 9 = 3x + 7 Solve for x, then plug that value of x into either equation and solve for y. That should get you going down the right path.
