Solve the equation <br> |x-3| -10=-5

Deffense [45]

Answer:

x=8 x=-2

Step-by-step explanation:

|x-3| -10=-5

Add 10 to each side

|x-3| -10+10=-5+10

|x-3| =5

Now separate into two equations , one positive and one negative

x-3 = 5 x-3 = -5

Add 3 to each side

x-3+3 = 5+3 x-3+3 = -5 +3

x=8 x=-2
