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