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