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