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 -b + 3b = b - 2y - 4 for b in terms of y.
| \(\frac{2}{11}\)y - \(\frac{4}{11}\) | |
| -\(\frac{2}{3}\)y - 2 | |
| 9y + 7 | |
| 2\(\frac{1}{2}\)y + 2 |
