Question

Show step by step for solving 4(k-2) = 2(k-9)

Answer 1

4(k-2) = 2(k-9)



open the parentheses

4k - 8 = 2k - 18

subtract 2k from both-side of the equation

4k - 2k - 8 = 2k - 2k - 18

2k - 8 = -18

Add 8 to both-side of the equation

2k - 8 + 8 = -18 + 8

2k = -10

Divide both-side of the equation by 2

k = -10/2

k= -5
