9 + 3 x + x + 7 = 2

x = - 3

Solution steps

9 + 3 x + x + 7 = 2

Remove square roots

4 x^{2} - 8 x + 4 = 16 x + 112

Solve

4 x^{2} - 8 x + 4 = 16 x + 112 : x = 9, x = - 3

x = 9, x = - 3

Verify Solutions:

x = 9

False

, x = - 3

True

The solution is

x = - 3

0 = 1 - x

7 = x + 1 + 4

14 - 5 x = x - 4

7 - 3 x + 3 = 8
