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 - 3b = -7b + z + 9 for b in terms of z.
| 3z - 1\(\frac{1}{3}\) | |
| 10z - 2 | |
| -\(\frac{6}{11}\)z - \(\frac{5}{11}\) | |
| 2z + 4\(\frac{1}{2}\) |
