Question

its a  question out of curiousity

Answer 1

Write it down like this:   

Let x=the number

4x+13=(1/2)x-8             the equation

4x-(1/2)x=(-8)-13          combine like terms

(3 1/2)x=-21                  simplify

(7/2)x=-21                    change 3 1/2 into a fraction

x=(-21)(2/7)                 multiply both sides by 2/7 to isolate x

x=-6
