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 -b + 9b = 9b - 8z - 3 for b in terms of z.
| -4z + \(\frac{2}{3}\) | |
| 1\(\frac{7}{10}\)z + \(\frac{3}{10}\) | |
| -1\(\frac{1}{4}\)z - \(\frac{1}{2}\) | |
| \(\frac{1}{5}\)z + \(\frac{3}{5}\) |
