3=7(4-2u)-6u

3 = 7 (4 - 2 u) - 6 u

u = \frac{5}{4}

Solution steps

3 = 7 (4 - 2 u) - 6 u

Switch sides

7 (4 - 2 u) - 6 u = 3

Expand

7 (4 - 2 u) : 28 - 14 u

28 - 14 u - 6 u = 3

Add similar elements:

- 14 u - 6 u = - 20 u

28 - 20 u = 3

Move

28

to the right side

- 20 u = - 25

Divide both sides by

- 20

u = \frac{5}{4}

x + \frac{3 x - 1}{2} = 3

19 - x = 30

6 x - 1 = 11

3 x + 8 + 5 x = 48

10 w - 2 = 28
