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 5b - 9b = 6b - 6z - 3 for b in terms of z.
| -2\(\frac{1}{5}\)z - \(\frac{1}{5}\) | |
| -\(\frac{2}{17}\)z - \(\frac{7}{17}\) | |
| -3z + 3 | |
| -2z + \(\frac{3}{7}\) |
