Question

Verify the following, when
a = -2
4a + 5(a – 1) = - 9​

Answer 1

Step-by-step explanation:

4(-2)+5{(-2)-1} => -8+5{-3} => -8-15 => -23

Answer 2

Step-by-step explanation:

To verify: 4a +5(a-1)=9

L.H.S. :. 4a+5(a-1)

On putting the value of a=-2 we get,

4(-2) + 5(-2 - 1)

= -8+(5*-3)

= -8 +(-15)

= -8 - 15

= -23

So, L.H.S. is not equal to R.H.S
