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