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 + 8b = -7b + 3z + 4 for b in terms of z.
| -\(\frac{5}{8}\)z + \(\frac{1}{2}\) | |
| -\(\frac{5}{8}\)z - \(\frac{5}{8}\) | |
| 1\(\frac{1}{8}\)z - \(\frac{1}{8}\) | |
| -\(\frac{7}{13}\)z + \(\frac{6}{13}\) |
