For this problem, it is telling you the value of y. So simply plug that in where the y is and then solve for x.
2x - 6 = 5x + 15 So what I would do is subtract 5x from each side to get:
-3x - 6 = 15 Now we can add six to both sides, to get rid of the negative 6.
-3x = 21 Now, to get x by itself, we need to divide each side by -3.
-3/-3 =1 We want 1x (or simply, x) on the left. On the right, 21/-3 = -7
So x = -7
