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