Equations
Equations are math problems with an equals sign.
An equals sign means that everything on one side of the equals sign is the SAME as everything on the other side of the equals sign.
How to solve an addition or subtraction equation using the opposite operation
For problems that look like this:
a number (by itself with no variable attached) + or - a variable (letter of the alphabet) = a number
5 + x = 15
x + 7 = 12
k – 14 = 26
13 – z = 9
