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 - 4b = -8b + z + 6 for b in terms of z.
| -5z - 1\(\frac{1}{2}\) | |
| -1\(\frac{1}{10}\)z - \(\frac{9}{10}\) | |
| z + 1\(\frac{1}{5}\) | |
| 10z - 1 |
