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 - 2c = -5c - 4y - 3 for c in terms of y.
| 1\(\frac{5}{7}\)y + \(\frac{6}{7}\) | |
| -1\(\frac{1}{7}\)y + \(\frac{3}{7}\) | |
| y - 1 | |
| -\(\frac{1}{5}\)y - \(\frac{3}{10}\) |
