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 + 9b = 7b + 8z - 2 for b in terms of z.
| \(\frac{1}{16}\)z + \(\frac{1}{8}\) | |
| 2\(\frac{1}{7}\)z - \(\frac{2}{7}\) | |
| 2\(\frac{1}{2}\)z - 1\(\frac{1}{2}\) | |
| -11z - 1 |
