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