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 + 4b = -9b + 4z + 4 for b in terms of z.
| z + \(\frac{4}{11}\) | |
| \(\frac{8}{9}\)z - 1 | |
| -1\(\frac{2}{3}\)z - \(\frac{2}{3}\) | |
| -\(\frac{7}{10}\)z + \(\frac{1}{2}\) |
