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 5b - 9b = -8b - 8y - 5 for b in terms of y.
| \(\frac{3}{10}\)y - \(\frac{1}{2}\) | |
| 1\(\frac{1}{13}\)y + \(\frac{5}{13}\) | |
| y - \(\frac{9}{11}\) | |
| \(\frac{1}{13}\)y - \(\frac{5}{13}\) |
