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 + 6c = -8c - 3y - 7 for c in terms of y.
| -1\(\frac{1}{8}\)y - \(\frac{1}{2}\) | |
| \(\frac{1}{3}\)y + \(\frac{7}{9}\) | |
| 13y + 2 | |
| -1\(\frac{2}{7}\)y - 1 |
