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 + 6b = 3b - 4y + 8 for b in terms of y.
| 14y + 2 | |
| -\(\frac{7}{9}\)y + \(\frac{4}{9}\) | |
| \(\frac{5}{6}\)y - \(\frac{2}{3}\) | |
| y - 2 |
