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 3b - 8b = 9b - 4z - 8 for b in terms of z.
| \(\frac{5}{16}\)z + \(\frac{5}{16}\) | |
| -\(\frac{2}{3}\)z + 1\(\frac{1}{3}\) | |
| 3z + 2\(\frac{1}{4}\) | |
| 1\(\frac{2}{3}\)z - 1\(\frac{2}{3}\) |
