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 -3b - 8b = -5b + 5y + 9 for b in terms of y.
| -1\(\frac{1}{7}\)y - \(\frac{5}{14}\) | |
| -\(\frac{1}{17}\)y - \(\frac{9}{17}\) | |
| -1\(\frac{5}{6}\)y + \(\frac{5}{6}\) | |
| 6\(\frac{1}{2}\)y + 4\(\frac{1}{2}\) |
