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 - 2c = -6c + 3y - 7 for c in terms of y.
| 16y - 1 | |
| -4y + 3 | |
| -1\(\frac{3}{5}\)y - \(\frac{7}{10}\) | |
| \(\frac{1}{3}\)y - \(\frac{7}{15}\) |
