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 -7b - 6b = -8b + 3z + 6 for b in terms of z.
| -4z - 3 | |
| 3z - \(\frac{1}{2}\) | |
| 9z + 6 | |
| -\(\frac{1}{2}\)z + \(\frac{3}{4}\) |
