1) Solve one of the equations for either variable.
2) Substitute the expression from Step 1 into the other equation.
3) Solve the resulting equation.
4) Substitute the solution in Step 3 into one of the original equations to find the other variable.
5) Write the solution as an ordered pair.
The answer is D.
Find common factors of denominators.
15+10+4/20= 29/20= 1 9/20 :)
Well $25 is the standard price initially.
$10 is added every hour as a constant rate.
Therefore a. 25 + 10h is the right expression
