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 - 4b = -2b + 3y - 9 for b in terms of y.
| -2\(\frac{1}{3}\)y + 3 | |
| \(\frac{1}{6}\)y + 1\(\frac{1}{2}\) | |
| -\(\frac{1}{9}\)y - 1 | |
| -y + \(\frac{3}{13}\) |
