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 + 9b = 6b + 6z + 2 for b in terms of z.
| -1\(\frac{4}{13}\)z - \(\frac{3}{13}\) | |
| -5\(\frac{1}{2}\)z - 2\(\frac{1}{2}\) | |
| \(\frac{3}{8}\)z - \(\frac{1}{4}\) | |
| 1\(\frac{1}{4}\)z - 2 |
