x=4/5(x+10)

2x/3+1=7x/15+3

3m=5m-8/5

**MathMate**, Saturday, July 12, 2014 at 6:02amI'll solve one, and will let you try the others as exercise.

x=(4/5)(x+10)

multiply by (5/4) on both sides:

5x/4 = x+10

subtract x from each side

5x/4-x =10

x/4=10

x=40

Check:

(4/5)(x+10)=(4/5)(40+10)=40=x ok.
