Question

find the value of x for which 4+(-7)= 2x-1​

Answer 1

Step-by-step explanation:

4 + (-7)= 2x-1

-3 = 2x-1

2x = -1+3

2x= 2

x=2/2

x=1

Answer 2

Answer:

x = - 1

Step-by-step explanation:

Given :

4 + ( - 7 ) = 2 x - 1​

We have to find value of x

First remove the bracket.

4 -7 = 2 x - 1​

Make variable one and constant one side.

2 x = 4 - 7 + 1

Now do simple calculation here

2 x = 5 - 7

2 x = - 2

x = - 1

Thus we get answer.

Verification:

4 -7 = 2 x - 1​

- 3 = 2 x - 1

put x = -1 here

R.H.S = 2 x - 1

R.H.S. = 2 × - 1 - 1

R.H.S. = - 2 - 1

R.H.S. = - 3

L.H.S. =  R.H.S.

Hence verified.
