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 7b + 8b = -b - 4z + 1 for b in terms of z.
| \(\frac{10}{11}\)z - \(\frac{9}{11}\) | |
| -z - 9 | |
| -1\(\frac{1}{2}\)z + \(\frac{1}{8}\) | |
| -\(\frac{1}{6}\)z - \(\frac{5}{12}\) |
