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 b - 4b = -9b - 6z - 6 for b in terms of z.
| \(\frac{2}{11}\)z + \(\frac{7}{11}\) | |
| -\(\frac{1}{5}\)z - \(\frac{3}{5}\) | |
| -z - 5 | |
| 3\(\frac{2}{3}\)z + 2\(\frac{2}{3}\) |
