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 -b + 5b = 7b - 4z - 6 for b in terms of z.
| -\(\frac{1}{10}\)z + \(\frac{9}{10}\) | |
| 1\(\frac{1}{8}\)z + \(\frac{3}{4}\) | |
| -\(\frac{4}{7}\)z - \(\frac{5}{7}\) | |
| -\(\frac{5}{8}\)z - \(\frac{1}{4}\) |
