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 -8c + c = 3c + 9y - 7 for c in terms of y.
| -\(\frac{2}{11}\)y - \(\frac{5}{11}\) | |
| -y + 2 | |
| -\(\frac{8}{11}\)y + \(\frac{7}{11}\) | |
| \(\frac{2}{7}\)y + \(\frac{1}{7}\) |
