Question

4(x+1) +5 = 2x - 3 give solutions ​

Answer 1

Answer:

-6

Step-by-step explanation:

4x+4+5=2x-3

4x+9=2x-3

4x-2x= -3-9

2x= -12

x= -6

Answer 2

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!
