Answer:
x = -37/8 or
= -4 5/8 or
= -4.625
Explanation:
First use distributive property on the left side. We don't even need the parenthesis on the right side, so we'll disappear those also.
10(x + 4) = (2x-1) + 4
10x + 40 = 2x - 1 + 4
Simplify the right side.
10x + 40 = 2x + 3
subtract 2x from both sides.
8x + 40 = 3
subtract 40 from both sides.
8x = -37
divide both sided by 8
x = -37/8
This is a perfectly good answer. Its neat and exact. But maybe you want a mixed number instead.
x = -4 5/8
(that's negative4 and 5/8s)
then also maybe you want you answer in decimal form
x = -4.625
This is also neat and exact.
