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