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