Reduce 5/8 with -5/8:
3x + 2x = 7/8
5x = 7/8
x = 7/40

3x + 5/8 + 2x - 5/8 = 7/8?
5x = 7/8
x = 7/40

3x + 2x = 5/8 - 5/8 + 7/8
3x + 2x = 7/8
x (3+2) = 7/8
8x = 7/(3+2)
8x = 7/5
x = 7/5 times 1/8
x = 7/40

First, observe that the 2nd and 4th term cancel each other out.
Contract the 1st and 3rd term and get:
5x = 7/8
Multiply both sides by 1/5 and get
5x / 5 = 7 / (8*5)
x = 7 / 40

3x+5/8+2x-5/8=7/8
5x=7/8(2 5/8's cancel out)
5x*1/5=7/8*1/5=7/40
x=7/40

5x= 7/8 Combine like terms
x= 7/40 Divide both sides by 5

3x + 5/8 + 2x - 5/8 = 7/8
3x + 2x = 7/8 - 5/8 + 5/8
5x = 7/8
x = 7/40
OK?

3X+5/8+2X-5/8 = 7/8
3X+2X +5/8-5/8 = 7/8
5X = 7/8
X = 7/8*5
X = 7/40
