Solve | 5+7= 17.
alisha [4.7K]

The solutions of the absolute value equation is determined as 15 and - 5.

<h3>Solution to the absolute equation</h3>

The solution to the absolute equation is determined as follows;

|x - 5| + 7 = 17

<em>collect similar terms</em>

|x - 5|  = 17 - 7

|x - 5|  = 10

<em>to resolve the absolute values, form two equations as follows;</em>

x - 5 = 10 and x - 5 = -10

x = 15 and x = -5

Thus, the solutions of the absolute value equation is determined as 15 and - 5.

The complete question is given as;

|x - 5| + 7 = 17
