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 -6b - 9b = -4b - 4z - 5 for b in terms of z.
| -\(\frac{1}{12}\)z + \(\frac{1}{4}\) | |
| \(\frac{1}{3}\)z + \(\frac{1}{12}\) | |
| -2\(\frac{1}{2}\)z + 2\(\frac{1}{2}\) | |
| \(\frac{1}{2}\)z - \(\frac{3}{4}\) |
