3x - 7 - 2x + 5 = 6

To solve the equation 3x - 7 - 2x + 5 = 6, we need to combine like terms on both sides of the equation.

Starting with the left side:
3x - 7 - 2x + 5

Combining like terms:
(3x - 2x) + (-7 + 5)
x - 2

Now we have:
x - 2 = 6

To isolate x, we need to get rid of the -2 on the left side by adding 2 to both sides of the equation:

x - 2 + 2 = 6 + 2

Simplifying:
x = 8

So the solution to the equation is x = 8.
