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