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 9b - 2b = -9b + 3z + 4 for b in terms of z.
| \(\frac{5}{18}\)z + \(\frac{2}{9}\) | |
| -1\(\frac{1}{3}\)z - 1\(\frac{2}{3}\) | |
| -z - 4 | |
| \(\frac{1}{4}\)z - 1 |
