Question

3. Given x=2 and y=-3, evaluate the expression given below 2x - 3xy - 2y? A) -28 B) 28 C) 8 D) 44

Answer 1

Given:-

x=2,y=-3

`2x-3xy-2y\text{?}`

To find evalute the given expression,

`2x-3xy-2y`

Subtitute the x and y value in above equation,

`\begin{gathered} 2(2)-3(2)(-3)-2(-3) \\ =4-(6*-3)+6 \\ =4-(-18)+6_{} \\ =4+18+6 \\ =28 \end{gathered}`

So the required value is 28.

So the correct option B.
