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 5b - 4b = -2b - 6z - 8 for b in terms of z.
| -\(\frac{2}{5}\)z - \(\frac{3}{5}\) | |
| 1\(\frac{1}{2}\)z - 1 | |
| -13z + 8 | |
| -\(\frac{2}{7}\)z - 1\(\frac{1}{7}\) |
