78=3t+66
Consider the second equation. Insert the known values of variables into the equation.
3t+66=78
Swap sides so that all variable terms are on the left hand side.
3t=78-66
Subtract 66 from both sides.
3t=12
Subtract 66 from 78 to get 12.
t=\frac{12}{3}
Divide both sides by 3.
t=4
Divide 12 by 3 to get 4.
p=78 t=4
The system is now solved.
