-5u plus 4 plus 8u equals 43?

Answer 1

-5u + 4 + 8u = 43

simplify by subtracting 4 from both sides of the equation to get rid of the 4 on the left:

-5u + 8u = 43

Simplify further by combining the -5u and the 8u:

3u = 43

Divide both sides by 3 to solve for u:

u = 43/3

rewrite the fraction:

u = 14 1/3
