I am kind of struggling here, it seems that there is absolute value in here, but w/ the 13= it is throwing me off. What  type of math is it? From there I can see if I can help you or not.

Positivity · Answer

well it is absolute value. do i like try and isolate x?

Positivity · Answer

wait-

Positivity · Answer

i found an example but it still doesn't make sense to me

Vocaloid · Answer

The absolute value signs || mean that 3x + 5 can either be 13 or -13, so you’d set up two equations

3x + 5 = 13
And 
3x + 5 = -13 and solve for both x-values

Positivity · Answer

ok ill try that real quick
