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