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 9c + 8c = 3c - 9y - 7 for c in terms of y.
| -\(\frac{3}{4}\)y - 1\(\frac{1}{4}\) | |
| -2\(\frac{5}{6}\)y - 1\(\frac{1}{6}\) | |
| -1\(\frac{1}{8}\)y + 1 | |
| -\(\frac{1}{8}\)y + \(\frac{1}{4}\) |
