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 -7b + 8b = -8b - 3z - 2 for b in terms of z.
| -\(\frac{1}{8}\)z - \(\frac{3}{16}\) | |
| 13z - 1 | |
| -\(\frac{7}{8}\)z + \(\frac{7}{16}\) | |
| -11z - 2 |
