1. 5(x-3)+ 5= 3(x+2)-4 original
5x - 15 + 5 = 3x + 6 - 4 distribute
5x - 10 = 3x + 2
2x = 12
x = 6
............................................
2. 3/4(x-2)+ 3/5= 1/5(x+1) original
(3/4(x-2)+ 3/5= 1/5(x+1))20 multiply the whole equation by 20 to delete fractions
15(x-2) + 12 = 4(x+1)
15x - 30 + 12 = 4x + 4
11x - 18 = 4
11x = 22
x = 2

3. one-third of sum of a number and seven
For this equation, what does (1/3)(x+7) equal?
