2^2q+2q+q=-7

2^{2} q + 2 q + q = - 7

q = - 1

Solution steps

2^{2} q + 2 q + q = - 7

Add similar elements:

2 q + q = 3 q

2^{2} q + 3 q = - 7

2^{2} = 4

4 q + 3 q = - 7

Add similar elements:

4 q + 3 q = 7 q

7 q = - 7

Divide both sides by

7

q = - 1

2 (3 x + 6) + 8 = 6 x

x, (f + h) (x) = 6 x - 4

- 5 z - 6 = 9

- 6 (8 + 4 n) = 2 (1 - 7 n)

x, g = f - f (- x)
