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