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 b - 3b = 7b - 8z - 6 for b in terms of z.
| 3\(\frac{2}{3}\)z - 1\(\frac{2}{3}\) | |
| -\(\frac{6}{13}\)z - \(\frac{7}{13}\) | |
| \(\frac{5}{6}\)z + 1 | |
| -2\(\frac{2}{3}\)z - 3 |
