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