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