The number is 5.

*A+ answer is 4 .:Sandy:.

21

18. 3 x 18 = 54 54 - 5 =49

Let the number be x:- If: 7x -22 = 125 Then: x = 21

7x - 4x = 27 3x = 27 x = 27/3 x = 9 Therefore, the number is 9. :)

141+20=161, 161/7=23. The answer is 23. It is algebra

The number is 8.... 7 x 8 = 56.... 2 x 8 = 16... 56 - 16 = 40

If the number, x, has 10 subtracted from twice it to make 28, then x must be 19. 2x - 10 = 28 2x = 38 x = 19

the number is 6.

The number is 26

7x - 25 = 15 7x = 40 x = 40/7 or 5 and 5/7

You said that " 7x - 4x = 30 ".From only that much information, I can see that 3x must be 30,which leads me directly to the realization that 'x' is 10 .

You said20 - 3x = 4 + x.Add 3x to each side of the equation:20 = 4 + 4xSubtract 4 from each side:16 = 4xDivide each side by 4 :4 = x

It is equivalent to multiplying by the cube of that number.

8-(2x)=10 -(2x)=10-8 -(2x)=2 x=2/(-2) x= -1

25-5x=85 -25 -25 -5x=60 60/-5=-12 x=-12

The answer is 23 itself 23 + 23 + 23 = 69 = 23 x 3 then 69 - 23 = 46

Let the number be x:- x-(25*4) = 63 x-100 = 63 x = 63+100 x = 163

3x - 20 = 46 3x = 46 + 20 3x = 66 x = 66/3 x = 22 Therefore, the number is 22! :)
