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 + b = -6b + z + 8 for b in terms of z.
| z + \(\frac{8}{9}\) | |
| \(\frac{1}{5}\)z - \(\frac{1}{2}\) | |
| -2\(\frac{1}{2}\)z + \(\frac{1}{2}\) | |
| -\(\frac{1}{7}\)z - 1 |
