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 -6b + 2b = 6b - 5z - 4 for b in terms of z.
| -\(\frac{1}{10}\)z + \(\frac{7}{10}\) | |
| -2\(\frac{3}{5}\)z - \(\frac{2}{5}\) | |
| \(\frac{7}{12}\)z + \(\frac{1}{3}\) | |
| 1\(\frac{2}{9}\)z - \(\frac{2}{3}\) |
