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 - 9c = -7c + 8y + 1 for c in terms of y.
| 2\(\frac{4}{5}\)y - 1\(\frac{4}{5}\) | |
| -3y + 2\(\frac{1}{2}\) | |
| 8\(\frac{1}{2}\)y + \(\frac{1}{2}\) | |
| \(\frac{2}{5}\)y - \(\frac{1}{5}\) |
