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 3b - 4b = -8b + 3z + 8 for b in terms of z.
| z - \(\frac{4}{7}\) | |
| -2\(\frac{1}{2}\)z + 2 | |
| -\(\frac{3}{10}\)z - \(\frac{7}{10}\) | |
| \(\frac{7}{11}\)z + \(\frac{8}{11}\) |
