4x-7=29 < do you understand how to set that up? Now, the goal is to “get x by itself.”
4x-7=29< now add the 7 to the 29. When you cross an equals sign you change the (+/-) sign of the number you’re moving.
4x= 36< now you will just divide by 4 on both sides. This will give you x by itself on the left side of the equals sign.
x=36/4 which is 9
X=9 :))
