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 + 8b = -9b - 5y - 5 for b in terms of y.
| -5y - 1\(\frac{1}{2}\) | |
| y - \(\frac{7}{8}\) | |
| \(\frac{9}{11}\)y + \(\frac{1}{11}\) | |
| -3\(\frac{1}{4}\)y - 1\(\frac{1}{4}\) |
