Question

) 2x(3x – 9) – 6x(x – 7) = 3 – (4x – 5) 

Answer 1

<=>6x²-18x-6x²-42x= 3-4x+5

<=>-60x=-4x+8

<=>-56x=8

<=> x=-7

Answer 2

`2x(3x-9)-6x(x-7)=3-(4x-5)`

`<=> 6x^2 -18x-(6x^2 - 42x) =3-4x+5`

`<=> 6x^2 -18x -6x^2 +42x=-4x+8`

`<=> 24x=-4x+8`

`<=> 24x+4x=8`

`<=> 28x=8`

`<=> x=8/28`

`<=>x= 2/7`
