Question

How many solution does 2x – 1 = 1 – 2x have?

Answer 1

one solution, x = 1/2

Explanation:

2x -1 = 1 -2x

solve using inverse operations

2x -1 = 1 - 2x

+1 +1

2x = 2 -2x

+ 2x +2x

4x = 2

/4 /4

x = 1/2

hence this equation has one solution x = 1/2

Answer 2

1

Explanation:

Hello,

2x – 1 = 1 – 2x

<=> 2x-1+2x=1

<=> 4x-1=1

<=> 4x = 1+1=2

<=> x = 2/4 = 1/2

Then there is only one solution.

Thanks
