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 2c + 3c = -5c - 9y + 6 for c in terms of y.
| y + 7 | |
| -\(\frac{3}{5}\)y - \(\frac{4}{5}\) | |
| -1\(\frac{5}{7}\)y + \(\frac{6}{7}\) | |
| -y + 1\(\frac{2}{7}\) |
