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 - 7b = 8b + 9z + 5 for b in terms of z.
| 2\(\frac{5}{6}\)z - \(\frac{5}{6}\) | |
| -\(\frac{4}{7}\)z + \(\frac{1}{14}\) | |
| -z - \(\frac{5}{16}\) | |
| \(\frac{8}{11}\)z + \(\frac{7}{11}\) |
