Remember that a negative number squared returns a positive so there are possible solutions
Example Question #41 : Two Step Equations
Solve for .
Add 3t to both sides to get the variable on one side of the equation. Then divide each side by 18 to get the answer.
Example Question #42 : Two Step Equations
Solve for .
Subtract 24 from each side to isolate the variable. Then divide each side by 72 to get x=3
Example Question #43 : Two Step Equations
Solve for .
Add 39g to each side to isolate the variable coefficient. Then divide each side by 21 to get .
Example Question #45 : Two Step Equations With Integers
Find the value of .
- 4 -4
/16 /16
Check your answer by substituting the value of X back into the equation. When solved both sides of the equation should be equal.
Example Question #46 : Two Step Equations
Solve for :
Solve for t in two steps. First move all constants to the opposite side. Then move constants attached to the variable you are solving for to the opposite side.
Subtract 2 from both sides:
The red terms cancel and the right side is subtracted as usual.
Divide both sides by 16:
The red terms cancel and the right side is divided as usual.
