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