.5(2x-14) = 6x+28
multiply .5 times the items in parenthesis
x - 7 = 6x + 28
add 7 to both sides of =
x = 6x +35
subtract 6x from both sides of =
-5x = 35
divide both sides of = by -5
x = -7

5(2x-14)=6x+28.
10x - 70 = 6x + 28
4x = 98
x = 98/4 = 49/2 = 24 1/2 = 24.5
The answer can be expressed as :
