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 - 2b = 8b + 3z + 4 for b in terms of z.
| -6z - 5 | |
| -\(\frac{5}{7}\)z - \(\frac{4}{7}\) | |
| -1\(\frac{1}{4}\)z - \(\frac{1}{4}\) | |
| -z + 2 |
