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