Answer 1

Answer:

pls mark me as the brainliest

Step-by-step explanation:

2x-6=0 is the correct answer

2x=0+6=6

x=6/2

x=3

Answer 2

Solution (check):

On substituting x = 3 on the equations, we get,

i) L.H.S. = 3 + 2 = 5 ≠ R.H.S.

ii) L.H.S. = 3 - 3 = 0 ≠ R.H.S.

iii) L.H.S. = 2 × 3 - 6 = 6 - 6 = 0 = R.H.S.

iv) L.H.S. = 9/3 = 3 ≠ R.H.S.

Answer:

iii) 2x - 6 = 0 has the solution as x = 3.
