A.)– 1
B.). – 7/2
C.)1
D.)7/2

how can you help me?​

Answer 1

On solving the equation:

3x-5 = 7x-9

-5+9 = 7x-3x

4 = 4x

4/4 = x

1 = x ---> This is the value of x.

Hence, by putting the value of x as 1, the equation will be true.

Let's put the value of x as 1 in the equation. Then,

3x-5 = 7x-9

3×1-5 = 7×1-9

3-5 = 7-9

-2 = -2, Hence Verified

Therefore option c) 1 is the right answer.

Answer 2

Answer:Option(c) 1 is the right answer

=>3x-5=7x-9

=>3x-7x=-9+5

=>-4x=-4

=>x=1
