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 - 8b = -b + 6z - 1 for b in terms of z.
| -14z + 1 | |
| -\(\frac{6}{13}\)z + \(\frac{6}{13}\) | |
| -\(\frac{7}{10}\)z - \(\frac{3}{5}\) | |
| \(\frac{3}{5}\)z - \(\frac{9}{10}\) |
