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