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 -8b + 4b = -3b + 6z + 8 for b in terms of z.
| -1\(\frac{7}{8}\)z + \(\frac{1}{2}\) | |
| -\(\frac{2}{5}\)z - 1\(\frac{3}{5}\) | |
| \(\frac{1}{4}\)z - 1\(\frac{1}{2}\) | |
| \(\frac{1}{4}\)z - \(\frac{1}{2}\) |
