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 - 6c = 7c + 9y + 1 for c in terms of y.
| 2\(\frac{1}{4}\)y + \(\frac{1}{2}\) | |
| -1\(\frac{1}{14}\)y - \(\frac{1}{14}\) | |
| 1\(\frac{1}{2}\)y - \(\frac{1}{8}\) | |
| -1\(\frac{2}{3}\)y + 1\(\frac{1}{3}\) |
