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 8c - 7c = 9c + 5y - 1 for c in terms of y.
| -\(\frac{7}{17}\)y - \(\frac{7}{17}\) | |
| -1\(\frac{1}{2}\)y - 1\(\frac{1}{6}\) | |
| \(\frac{1}{2}\)y - \(\frac{1}{4}\) | |
| -12y + 1 |
