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 c + 8c = -c + 9y + 7 for c in terms of y.
| \(\frac{5}{17}\)y - \(\frac{3}{17}\) | |
| y + 1\(\frac{1}{2}\) | |
| 2\(\frac{2}{3}\)y + 1 | |
| \(\frac{1}{2}\)y + 3\(\frac{1}{2}\) |
