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 - 9c = -4c - y + 1 for c in terms of y.
| \(\frac{11}{13}\)y + \(\frac{4}{13}\) | |
| 3\(\frac{1}{2}\)y + \(\frac{1}{2}\) | |
| -2\(\frac{2}{3}\)y - \(\frac{1}{3}\) | |
| \(\frac{8}{11}\)y - \(\frac{9}{11}\) |
