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