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 -5c + 4c = -9c - 8y + 6 for c in terms of y.
| -3y + 1\(\frac{1}{2}\) | |
| -y - 2\(\frac{2}{3}\) | |
| 7y + 3 | |
| -1\(\frac{2}{15}\)y + \(\frac{3}{5}\) |
