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 - 4b = -5b - 3z + 9 for b in terms of z.
| \(\frac{1}{10}\)z + \(\frac{1}{10}\) | |
| \(\frac{1}{11}\)z + \(\frac{9}{11}\) | |
| -\(\frac{1}{2}\)z - \(\frac{1}{2}\) | |
| -15z + 5 |
