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 2b + 8b = 8b - 7z + 5 for b in terms of z.
| -\(\frac{4}{5}\)z + \(\frac{9}{10}\) | |
| 2z - 2\(\frac{1}{3}\) | |
| 2\(\frac{1}{2}\)z - \(\frac{5}{6}\) | |
| \(\frac{1}{2}\)z + \(\frac{1}{6}\) |
