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 + 9c = 3c + 7y + 3 for c in terms of y.
| -\(\frac{5}{13}\)y - \(\frac{7}{13}\) | |
| 10y + 7 | |
| -3y + 7 | |
| \(\frac{2}{11}\)y - \(\frac{3}{11}\) |
