2.  Equation-math sentence that contains an equal sign  Variable-unknown letter  Inverse-opposite  To solve equations, do the opposite operation  GOAL: get the variable by itself!  The equation works like a balenced scale..what you do to one side you HAVE to do to the other side!

3.  N +3=12  B+10=50  X-8=2  c-12=75  *Check your work by putting in the number you get for the variable..if it works it is right!

4.  To solve, do the opposite  Ex) 8n=16Ex) 45n=900  Ex) t/6=20Ex) b/7=10
