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