Question

I need to know how to solve this problem because I’m very confused and it doesn’t explain what it is or how to do it in my textbook

Answer 1

x1 = -4; x2 = 10

Explanation:

1) Expand the module as two separate equations:

x - 3 = 7

x - 3 = -7

2) Solve the equations:

x = 10

x = -4

=> x1 = -4; x2 = 10
