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 -2b - 7b = -3b + 2z - 3 for b in terms of z.
| -\(\frac{1}{2}\)z + 1 | |
| 9z - 3 | |
| \(\frac{5}{7}\)z - \(\frac{2}{7}\) | |
| \(\frac{3}{8}\)z - \(\frac{1}{4}\) |
