Question

3x+2 (x+3) =21
$3x + 2 (x + 3) = 21$

Answer 1

HERE YOUR ANSWER:-
$3x + 2(x + 3) = 21 \\ 3x + 2x + 6 = 21 \\ 3x + 2x = 21 - 6 \\ 5x = 15 \\ x = 15 \div 5 \\ x = 3$
The value of x is 3.


VERIFICATION:-
$3x + 2(x + 3) = 21 \\ 3 \times 3 + 2(3 + 3) = 21 \\ 9 + 2 \times 6 = 21 \\ 9 + 12 = 21 \\ 21 = 21$
Here, L.H.S=R.H.S
So, value of x is 3


HOPE IT HELPS YOU!
