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 + 7b = 5b - 9z + 1 for b in terms of z.
| -7z + 8 | |
| 2\(\frac{2}{3}\)z - \(\frac{1}{6}\) | |
| \(\frac{1}{2}\)z - 1\(\frac{1}{2}\) | |
| \(\frac{1}{4}\)z - \(\frac{5}{12}\) |
