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 2b + 8b = -8b + z - 6 for b in terms of z.
| -\(\frac{7}{10}\)z - \(\frac{3}{5}\) | |
| -8z - 1 | |
| -2z + 2\(\frac{2}{3}\) | |
| 1\(\frac{4}{5}\)z + \(\frac{2}{5}\) |
