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 -4c + 8c = 9c + 8y + 3 for c in terms of y.
| -\(\frac{4}{7}\)y - \(\frac{3}{7}\) | |
| 13y + 3 | |
| \(\frac{9}{11}\)y + \(\frac{6}{11}\) | |
| y - \(\frac{3}{13}\) |
