Question

Check whether 3 is the root of the equation 2x – 17 = 5

Answer 1

Answer:

2x-17=5 2x=17+5 2×=22 ×=22/2

×=11 so 3 is the no root of 11

Answer 2

Answer:

No, it can not be the root of the given equation.

Step-by-step explanation:

Given equation,

$2x - 17 = 5$

Substitute x = 3 in the left side of the equation,

L.H.S.

$2(3) - 17$

$=6 - 17$

$=-9$

≠ 5

≠ R.H.S

Hence, we can say that,

3 can not be the root of the equation $2x-17=5$
