Haha, sturdy success with that English degree.... i'm beneficial there is diverse jobs waiting for you once you graduate... remember, in math, once you have an equation, notwithstanding you do to a minimal of one part you need to do to the different. So, we are able to enhance the two sides to the (3/4) potential. This then leaves us with: (x+3) = sixteen^(3/4) = (x+3) = 8 Then isolate x and we get x = 5 we are able to examine our artwork and plug 5 back into the 1st equation and positively, we get the striking answer.

well you should distribure the -4
4x-12=16
next ad 12 to each side
4x=28
Devide by 4
x=28/4
so
x=7
Ok here is the Check
-4(-7+3)=16
add -7 to 3
-4(-4)=16
multply -4*-4
16=16
that means that it works so x is 7

-4(-x+3)=16
using distributive property
4x+(-12)=16
4x-12=16
add 12 to both sides
4x=28
divide both sides by 4
x=7
