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