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 - z + 6 for b in terms of z.
| -5z + 4 | |
| -\(\frac{5}{12}\)z - \(\frac{5}{12}\) | |
| -4z - 8 | |
| 1\(\frac{1}{6}\)z + 1 |
