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 + 4z + 2 for b in terms of z.
| -7z + 8 | |
| 5z - 3 | |
| 1\(\frac{1}{2}\)z + \(\frac{1}{4}\) | |
| \(\frac{6}{11}\)z - \(\frac{5}{11}\) |
