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