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 4c - 8c = 9c + 6y - 8 for c in terms of y.
| -2\(\frac{4}{5}\)y + 1\(\frac{3}{5}\) | |
| \(\frac{1}{9}\)y - \(\frac{8}{9}\) | |
| -1\(\frac{1}{2}\)y + 4 | |
| -\(\frac{3}{11}\)y - \(\frac{8}{11}\) |
