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 -8c - 7c = -6c - y + 7 for c in terms of y.
| -y + 3\(\frac{1}{2}\) | |
| -\(\frac{1}{6}\)y + \(\frac{1}{4}\) | |
| -3y - 3\(\frac{1}{2}\) | |
| 1\(\frac{4}{7}\)y - \(\frac{5}{7}\) |
