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 - 7b = 3b + 3z - 6 for b in terms of z.
| -2z + 1\(\frac{1}{5}\) | |
| 6z + 2 | |
| -\(\frac{5}{6}\)z + \(\frac{7}{12}\) | |
| -\(\frac{3}{8}\)z - 1\(\frac{1}{8}\) |
