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 - 5b = 4b - 8z - 2 for b in terms of z.
| -5\(\frac{1}{3}\)z + \(\frac{2}{3}\) | |
| -\(\frac{4}{5}\)z - \(\frac{3}{10}\) | |
| -\(\frac{3}{10}\)z + \(\frac{3}{10}\) | |
| \(\frac{1}{4}\)z + \(\frac{1}{6}\) |
