-2 - (4X) = 10
-2 + 2 - (4X) = 10 + 2
4X = 12
4x/4 = 12/4
X = 3

-2 - (-4 * 3) = 10
-2 - (-12) = 10
-2 + 12 = 10
10 = 10

4x - (-2) = 10

you cannot minus a negative so, the problem will become addition

4x + 2 = 10

then subtract 2 from both sides. Problem reads now

4x = 8

Divide both sides by 4

x = 2

Let the number be y
By question,
-2- 4(times the number) = 10
i.e. -2 - 4y = 10
i.e. -2 - 10 = 4y
i.e. -12 = 4y
i.e -12/4 = y
i.e. y = -3
So, the required number is -3.

Now solve the other related problems by yourself.
