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 - b = 3b + 4z - 8 for b in terms of z.
| -1\(\frac{1}{4}\)z + 2 | |
| -\(\frac{11}{14}\)z + \(\frac{3}{14}\) | |
| -4\(\frac{1}{2}\)z - 1 | |
| -\(\frac{1}{5}\)z - 1\(\frac{2}{5}\) |
