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 7c + c = 9c + 5y + 2 for c in terms of y.
| -1\(\frac{3}{5}\)y - \(\frac{1}{5}\) | |
| -2y - 1 | |
| -1\(\frac{4}{5}\)y + 1\(\frac{2}{5}\) | |
| -\(\frac{1}{17}\)y + \(\frac{4}{17}\) |
