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 + 9c = c - 6y - 3 for c in terms of y.
| \(\frac{1}{8}\)y - \(\frac{7}{16}\) | |
| 1\(\frac{7}{8}\)y + \(\frac{3}{8}\) | |
| \(\frac{10}{11}\)y - \(\frac{9}{11}\) | |
| 6y - 3 |
