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