7x+0=2x+18+2x+18

7 x + 0 = 2 x + 18 + 2 x + 18

x = 12

Solution steps

7 x + 0 = 2 x + 18 + 2 x + 18

7 x + 0 = 7 x

7 x = 2 x + 18 + 2 x + 18

Group like terms

7 x = 2 x + 2 x + 18 + 18

Add similar elements:

2 x + 2 x = 4 x

7 x = 4 x + 18 + 18

Add the numbers:

18 + 18 = 36

7 x = 4 x + 36

Move

4 x

to the left side

3 x = 36

Divide both sides by

3

x = 12

6 x - 4 + 2 x = 4 (5 + 2 x)

(5 r^{3})^{\frac{1}{4}}

∣ x + 4 ∣ = 0

a = \frac{1}{2} π (12.9)^{2}

\frac{125}{10}
