Question

`|x + 9| - 4 = 2x`
Find the find the solutions
​

Answer 1

x = 5 when x >=-9

Explanation:

| x + 9 | - 4 = 2x

x + 9 - 4 = 2x

x - 2x = 4 - 9

-x = - 5

x = 5

x < - 9 no solution

| x + 9 | - 4 = 2x

| -10 + 9 | - 4 = 2(-10)

| -1 | - 4 = -20

1 - 4 = -20

-3 = -20

x >= -9 no solution only x = 5

| x + 9 | - 4 = 2x

| -9 + 9 | - 4 = 2(-9)

| -1 | - 4 = -18

1 - 4 = -18

-3 = -18
