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 -6b + 8b = 8b + 5z - 5 for b in terms of z.
| -1\(\frac{1}{7}\)z + \(\frac{4}{7}\) | |
| \(\frac{5}{9}\)z - \(\frac{8}{9}\) | |
| \(\frac{3}{14}\)z + \(\frac{5}{14}\) | |
| \(\frac{8}{11}\)z - \(\frac{2}{11}\) |
