-11= 61-6q
Use PEMDAS backwards:
look for addition and subtraction left from right across the line and do the opposite operation.
look at the 61 it is positive so subtract it.
-11-61 = -6q
-72 = -6q
now look for mulitplication and division across the line left to right.
look at -6q and divide by -6
-72/-6 = q
12 = q that is your answer if there were more you go further.
look for exponet and do the opposite, take the square root or third root, etc.
then do the opposite operation of the operation in the parenthesis.
