Question

Solve for u.
7(u-1) = 3u + 1-2(-9u-2)
Simplify your answer as much as possible.

Answer 1

u=-0.86

Explanation:

Step 1: distribute values: 7u-7=3u+1+18u+4

Step 2: combine like terms: 7u-7=21u+5

Step 3: move the -7 over by adding 7 to both sides: 7u=21u+12

Step 4: move the 21u over by subtracting 21u from both sides: -14u=12

Step 5: divide by -14 and you get u=-0.86

Hope that helps
