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