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 - 4b = 5b + 5z + 8 for b in terms of z.
| 2\(\frac{1}{4}\)z + 2 | |
| \(\frac{2}{3}\)z - \(\frac{1}{5}\) | |
| \(\frac{1}{14}\)z - \(\frac{3}{7}\) | |
| -\(\frac{7}{16}\)z - \(\frac{9}{16}\) |
