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 -3b - 3b = 5b + 9z + 6 for b in terms of z.
| z + 2 | |
| -1\(\frac{1}{2}\)z - \(\frac{3}{4}\) | |
| \(\frac{3}{14}\)z + \(\frac{3}{7}\) | |
| -1\(\frac{6}{13}\)z - \(\frac{7}{13}\) |
