15x + 8 - 14x - 15 = 3
x + 8 - 15 = 3
x - 7 = 3
x - 7 + 7 = 3 + 7
x = 10
The answer is x = 10
insert the x value into the equation
- - - - - - - - - - - - - - - - - - - - - - -
Check
15x + 8 - 14x - 15 = 3
15(10) + 8 - 14(10) - 15 = 3
150 + 8 - 140 - 15 = 3
158 - 140 - 15 = 3
18 - 15 = 3
3 = 3

I'm guessing we're solving for X
15x + 8 -14x -15 =3
The first thing you want to do is move all the numbers to one side of the equation, so you have all the x's on one side and all the numbers on the other.
So we are going to subtract 8 from both sides then add 15 to both sides.
15x + 8 - 8 - 14x - 15 + 15 = 3 - 8 + 15
Now simplify
15x - 14x = 10
Now combine your x terms
1x = 10
x = 10

15x-14x-7=3 (simplifying 8-15=7)
x-7=3 (simplifying 15x-14x=x)
x=3+7
x=10
