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 6c - c = -3c - 5y + 7 for c in terms of y.
| -1\(\frac{1}{7}\)y - \(\frac{3}{7}\) | |
| -y + 1\(\frac{3}{4}\) | |
| -\(\frac{4}{9}\)y + \(\frac{7}{9}\) | |
| 3y - 4 |
