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 5b - 7b = -9b + 8z + 5 for b in terms of z.
| 1\(\frac{1}{14}\)z + \(\frac{5}{14}\) | |
| -3\(\frac{1}{2}\)z + 2\(\frac{1}{2}\) | |
| 1\(\frac{1}{7}\)z - \(\frac{2}{7}\) | |
| \(\frac{3}{5}\)z + 1 |
