8x-16=4x+4
when solving equations try to get the variable on just one side and the non-variables on the other. In this problem lets first subtract 4x from both sides.
8x-16=4x+4
-4x -4x
4x-16=4
Now add 16 to both sides this will leave all the xs in one side and all of the non x on the other.
4x-16=4
+16 +16
4x=20
Now to leave the x by itself divide both sides by 4.
4x=20
/4 /4
x=5
That's your final answer.
