We need to substitute the given values into the expression, that is
![-5(-3-10)](https://img.qammunity.org/2023/formulas/mathematics/college/qfwrqno7wpy1xiy38xp16lgr6k8kjqs9p4.png)
the term into the parenthesis is equal to -3-10=-13, then our last expression is equivalent to
![-5(-13)](https://img.qammunity.org/2023/formulas/mathematics/college/ldypx4vamkcximdud8dq7cooeud3f2gnx9.png)
By making the product and taking into account the law of signs (minus times minus equal plus), we have
![-5(-13)=65](https://img.qammunity.org/2023/formulas/mathematics/college/kwdn65v1t7g91rfia9s4e5sjvxduhpfbi4.png)
Then, What is the value of x(y-10)? answer: 65
