Question

If x=-5 and y=-3 What is the value of x(y-10)?

Answer 1

We need to substitute the given values into the expression, that is

$-5(-3-10)$

the term into the parenthesis is equal to -3-10=-13, then our last expression is equivalent to

$-5(-13)$

By making the product and taking into account the law of signs (minus times minus equal plus), we have

$-5(-13)=65$

Then, What is the value of x(y-10)? answer: 65
