Solve the equation 6x+7=8x-15

X = 11

Step-by-step explanation:

So, in order to solve this equation, we need to isolate x.

So, we are going to subtract 8x from the right side to get the x on one side. The equation should look like this:

-2x + 7 = -15

Now in order to get x all alone on one side, we need to subtract 7 from the left side.

-2x = -22

Now we just have to divide the -2 from x.

X = 11
