4a-2(a+9)=6

4 a - 2 (a + 9) = 6

a = 12

Solution steps

4 a - 2 (a + 9) = 6

Expand

- 2 (a + 9) : - 2 a - 18

4 a - 2 a - 18 = 6

Add similar elements:

4 a - 2 a = 2 a

2 a - 18 = 6

Move

18

to the right side

2 a = 24

Divide both sides by

2

a = 12

8 x + 6 x = 8 x + 4 x + 12

7 p^{2} = - 6 p + 3

\frac{2}{3} m + 14 = 0

4 y^{3} - 4 y^{2} - 24 y

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