Question

Solve the equation. Check your solutions. | x +3 |=9

Answer 1

The solution is 6 0r -12

Explanation:

| x +3 |=9​

| x +3 | means x+3 or -(x+3)

When it x + 3

x + 3 = 9

x = 9-3

x = 6

When it is -(x+3)

-(x+3) = 9

-x - 3 = 9

-x = 9 + 3

-x = 12

Divide through by -1

-x/-1 = 12/-1

x = -12

The solution is 6 0r -12
