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 + 2b = 5b - 8y + 9 for b in terms of y.
| 2\(\frac{1}{2}\)y - 2\(\frac{1}{4}\) | |
| -\(\frac{8}{11}\)y - \(\frac{9}{11}\) | |
| -\(\frac{2}{3}\)y - 1\(\frac{1}{6}\) | |
| 6\(\frac{1}{2}\)y + 3\(\frac{1}{2}\) |
