7w+7(w+2)=28

7 w + 7 (w + 2) = 28

w = 1

Solution steps

7 w + 7 (w + 2) = 28

Expand

7 (w + 2) : 7 w + 14

7 w + 7 w + 14 = 28

Add similar elements:

7 w + 7 w = 14 w

14 w + 14 = 28

Move

14

to the right side

14 w = 14

Divide both sides by

14

w = 1

x, 11 x + 9 = 5 x = 15

(2 x + 1)^{2} = 4 (x^{2} + x + 1)

6 - \frac{x}{7} = \frac{x}{8}

a (x + b) - c = d

\frac{x}{3} = 20
