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 - 8b = -4b + 2z - 7 for b in terms of z.
| 1\(\frac{2}{3}\)z - \(\frac{1}{6}\) | |
| 3z - 1\(\frac{1}{2}\) | |
| -1\(\frac{1}{4}\)z + \(\frac{3}{8}\) | |
| 10z - 7 |
