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 -3b + 8b = 8b - z - 2 for b in terms of z.
| -\(\frac{1}{4}\)z + \(\frac{3}{8}\) | |
| -1\(\frac{2}{5}\)z - \(\frac{3}{5}\) | |
| \(\frac{9}{11}\)z + \(\frac{2}{11}\) | |
| \(\frac{7}{8}\)z + \(\frac{3}{8}\) |
