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