Hey there :)
3x + 5 = - 16x
It is ideal to take the like-terms together
Take 3x to the other side { Do subtraction since the operation is addition on the left hand side }
3x ( - 3x ) + 5 = - 16x - 3x
5 = - 19x
Divide by - 19 on either side to isolate x
[tex] \frac{5}{-19} = \frac{-19x}{-19} [/tex]
x = [tex]- \frac{5}{19} = -0.2631578947[/tex]
