x+x+(x+12)=180

x + x + (x + 12) = 180

x = 56

Solution steps

x + x + (x + 12) = 180

Remove parentheses:

(a) = a

x + x + x + 12 = 180

Add similar elements:

x + x + x = 3 x

3 x + 12 = 180

Move

12

to the right side

3 x = 168

Divide both sides by

3

x = 56

5 v^{2} + 20 v + 10 = 4 v

\frac{1}{5} x + \frac{1}{2} = - 4 (\frac{3}{4} x - 4)

\frac{3}{4} x = 2

(x - 2)^{2} + (x + 1)^{2} = 3

\frac{- 2 - 4 i}{7 i}
