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 = -4c - 3y + 1 for c in terms of y.
| 4y - 1 | |
| -\(\frac{2}{5}\)y + \(\frac{9}{10}\) | |
| 1\(\frac{3}{4}\)y - \(\frac{3}{8}\) | |
| \(\frac{3}{7}\)y - \(\frac{3}{7}\) |
