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 9b + 2b = 4b - 4z + 6 for b in terms of z.
| -3z + 1 | |
| -11z + 9 | |
| -\(\frac{7}{17}\)z - \(\frac{7}{17}\) | |
| -1\(\frac{1}{5}\)z + 1\(\frac{1}{5}\) |
