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