how do you solve for x+2=7 in algerbra
The equal sign means you have to keep both sides equal.
What you do to one side, you have to do to the other side.
In this case x + 2 = 7
you want the x to be by itself on one side. There's a
two over there so you have to subtract it. When you
subtract two from one side, you also have to subtract
the same two from the other side.
x +2 – 2 = 7 – 2
x = 5
and there's your answer: x = 5
