Question

3x+2(x+2)=20-(2x-5)solve with Verification

Answer 1

Answer:

3x + 2x + 4 = 20 - 2x + 5

5x + 2x = 20 - 4 + 5

7x = 21

x = 21/7 = 3

Verification:

3(3) + 2(3 + 2) = 20 -(2(3) - 5)

9 + 2(5) = 20 - ( 6 - 5)

9 + 10 = 20 -(1)

19 = 19

Therefore, L.H.S = R.H.S

Answer 2

➡️ SOLUTION

$3x + 2(x + 2) = 20 - (2x - 5)$

$3x + 2x + 4 = 20 - 2x + 5$

$5x + 4 = 25 - 2x$

on taking x-terms one side and constants one side...

$5x + 2x = 25 - 4$

$7x = 21$

$x = \frac{21}{7}$

$x = 3$

Answer...

NOW, For Verification :-

PUT THE VALUE OF X IN THE EQUATION...(x= 3)....

$3x + 2(x + 2) = 20 - (2x - 5)$

$3 \times 3 + 2(3 + 2) = 20 - (2 \times 3 - 5)$

$9 + 2 \times 5 = 20 - (6 - 5)$

$9 + 10 = 20 - 1$

$19 = 19$

L.H.S = R.H.S

HENCE , VERIFIED !
