Answer 2

• As per the data given in the question, we have to determine the value of the given expression.

        Given data:- $-3x+5x-15.$ where $x=(-7).$

        To find:- the value of given expression=?

        Solution:-

        According to the condition, we have to put the value of $x=-7.$

        So we get,

        $\Rightarrow -3x+5x-15\\\Rightarrow -3\times-7+5\times-15\\\Rightarrow 21-35-15\\\Rightarrow -29.$

       Hence, the value will be $-29.$
