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 -2b + 9b = 8b - 2z - 5 for b in terms of z.
| -5z - 3 | |
| 2z - 4 | |
| 1\(\frac{1}{10}\)z + \(\frac{1}{2}\) | |
| z + \(\frac{1}{4}\) |
