When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 7c - 5c = 4c - 5y - 5 for c in terms of y.
| 2y + \(\frac{1}{3}\) | |
| y - 1\(\frac{2}{3}\) | |
| -1\(\frac{1}{3}\)y - 1\(\frac{2}{3}\) | |
| 2y + 1\(\frac{1}{6}\) |
