Usually 7x or 10x, but if the binocular lens is bigger than 80mm in diameter, maybe 12x or 15x.
(3x+2)-(5+7x) = 3x+2-5-7x = -4x-3 3x+2 is -4x-3 times greater than 5+7x.
7x-5
7x^3. That is 7x cubed.... or 7x*7x*7x (where * means multiply). You should get 343x
Let the number be x: 7x-6 = -20 7x = -20+6 7x = -14 x = -2
2x-6 < 5+7x 2x-7x < 5+6 -5x < 11 x > -2.5

You're asking for the difference: (3x + 2) - (5 - 7x).(3x + 2) - (5 - 7x) =3x + 2 - 5 + 7x =10x - 3.It is (10x - 3) greater.

Could you write a longer question? Generally, the x means times. Like my hand is seven times bigger than my son's hand. But if it's clothing it means extra-large.
