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 = -6b + 8z + 1 for b in terms of z.
| 1\(\frac{7}{8}\)z + \(\frac{1}{8}\) | |
| 1\(\frac{2}{5}\)z - 1\(\frac{2}{5}\) | |
| \(\frac{4}{11}\)z - \(\frac{2}{11}\) | |
| \(\frac{7}{12}\)z - \(\frac{3}{4}\) |
