Question

3(2x+1)+7=6x-3-2(2-4x)
What is x?
Give as an improper fraction in its simplest form

Answer 1

Explanation:

Use distributive property:a*(b +c) = (a*b) + (a*c)

3(2x + 1) + 7 = 6x - 3 - 2(2-4x)

3*2x + 3*1 +7 = 6x - 3x -2*2 + (-2)*(-4x)

6x + 3 + 7 = 6x - 3 - 4 + 8x

6x + 10 = 14x - 7

6x - 14x = - 7 - 10

-8x = -17

x = -17/-8

x = 17/8
