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 5c + 7c = 8c - 5y - 1 for c in terms of y.
| -1\(\frac{1}{4}\)y - 2\(\frac{1}{4}\) | |
| -4y + 3 | |
| 4y + \(\frac{1}{3}\) | |
| 2y - \(\frac{3}{4}\) |
