Question

how do you solve 5/3 (1/2x – 5) = 3x + 15

Answer 1

Favorite Answer

5/3(1/2x - 5) = 3x + 15

(Multiply by 3)

5(1/2x - 5) = 9x + 45

(Distribute the 5)

5x/2 - 25 = 9x + 45

(Subtract 9x from both sides, and add 25)

5x/2 - 9x = 45 + 25

(Factor out the x)

x(5/2 - 9) = 70

x(-13/2) = 70

(Multiply by -2 and divide by 13)

x = -140/13
