Question

Solve the equation |x+4| = 5

I don't know what the steps are for this sort of equation. Please can someone help?

Answer 1

the absolute value sign makes what is inside positive.
we do this by
1) assume x+4 is positive. if it is, then we can drop the abs val sign
x+4= 5
solve for x
2) assume (x+4) is negative. we know the | | will make it positive
to make it positive we can multiply by -1
in other words -1*(x+4) will be positive, and we drop the | |
solve
-1*(x+4)= 5

Answer 2
