Example of Simplifying 7(1)+9(3)5(3)2\frac{7(-1)+9(-3)}{-5(3)-2}

To simplify the expression 7(1)+9(3)5(3)2\frac{7(-1)+9(-3)}{-5(3)-2}, calculate the expressions above and below the fraction bar separately before dividing.

In the numerator, complete the multiplication: 7(1)=77(-1) = -7 and 9(3)=279(-3) = -27. Add them to get 7+(27)=34-7 + (-27) = -34. In the denominator, compute the multiplication: 5(3)=15-5(3) = -15. Subtract to get 152=17-15 - 2 = -17. The expression simplifies to 3417\frac{-34}{-17}. Dividing the values yields 22.
