Answer :-
- The required number is -6.
Step-by-step explanation:
Given that,
- 4 ( x + 1 ) + 5 = 2x - 3
=> 4 ( x + 1 ) + 5 = 2x -3
=> (4)(x) + (4)(1) + 5 = 2x -3
=> 4x + (4)(1) + 5 = 2x -3
=> 4x + 4 + 5 = 2x -3
=> 4x + 9 = 2x -3
=> 4x - 2x = -3 -9
=> 2x = -12
=> x = -12/2
=> x = -6
Hence, The required number is -6.
Now, Verification
Given,
- L.H.S = 4 ( x + 1 ) + 5
- R.H.S = 2x - 3
By putting the value of x on both L.H.S and R.H.S,
- L.H.S
=> 4 ( x + 1 ) + 5
=> 4 ( -6 + 1 ) + 5
=> 4 (-5) + 5
=> (4)(-5) + 5
=> -20 + 5
=> -15
Now, L.H.S = -15
- R.H.S
=> 2x - 3
=> (2)(-6) - 3
=> -12 - 3
=> -15
Now, R.H.S = -15
Therefore,
- L.H.S = -15
- R.H.S = -15
L.H.S = R.H.S
Hence, Verified!
