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