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