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