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 7b - 7b = -8b - 4y + 4 for b in terms of y.
| \(\frac{1}{5}\)y + \(\frac{4}{15}\) | |
| -\(\frac{2}{5}\)y + 1 | |
| 14y - 3 | |
| 7y + 2 |
