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