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 + 2b = 9b + 4z - 2 for b in terms of z.
| -\(\frac{1}{4}\)z + \(\frac{1}{4}\) | |
| -3z + 2 | |
| -\(\frac{2}{11}\)z - \(\frac{3}{11}\) | |
| -\(\frac{12}{13}\)z - \(\frac{2}{13}\) |
