Question 629469
5u + 6 - 3(4u - 1) = 3(u - 1)

-3 * 4u = -12u

-3 * -1 = 3

3 * u = 3u

3 * -1 = -3


5u + 6 - 12u + 3 = 3u - 3

Combine like terms:

5u - 12u = -7u

6 + 3 = 9


-7u + 9 = 3u - 3

Add 3 to each side of the equation

-7u + 9 + 3 = 3u - 3 + 3

Combine like terms:

9 + 3 = 12

-3 + 3 = 0

-7u + 12 = 3u

Add 7u to each side of the equation

-7u + 12 + 7u = 3u + 7u

Combine like terms:

-7u + 7u = 0

3u + 7u = 10u

12 = 10u or

10u = 12

Divide each side by 10

10u/10 = 12/10

u = 12/10 = 6/5 = 1 1/5

The Answer:

u = 6/5 = 1 1/5
