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 + 9b = -b - 7z - 2 for b in terms of z.
| -\(\frac{3}{10}\)z + \(\frac{2}{5}\) | |
| -16z - 2 | |
| z + 1\(\frac{3}{4}\) | |
| 1\(\frac{4}{5}\)z - 1\(\frac{1}{5}\) |
