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 9c + c = c + 8y + 6 for c in terms of y.
| -3\(\frac{1}{4}\)y + \(\frac{1}{2}\) | |
| \(\frac{7}{8}\)y + \(\frac{3}{4}\) | |
| y - 3 | |
| -\(\frac{5}{8}\)y - \(\frac{3}{4}\) |
