the set up is 6(x-20)=4x solving for x you get 60.
Another answer: If the number times 6 gives X this can be writen as...
6n = X
and if 6n - 20 = 4 times the numberthis can be writen as...
6n - 20 = 4n
so, 4n + 20 = 6n
so 20 = 2n
so 10 = n
the number is 10
How do you write half a number decreased by 8 is equal to the sum of the number and 14
3x+32=4x-15 3x-4x=-15-32 x=-47
The answer is: 2 or -2

Either 2*(n-4) = 2n - 8 or 2n - 4 It depends on whether the "twice" operates on "the number decreased by 4" or "the number".

How do you write half a number decreased by 8 is equal to the sum of the number and 14
3x+32=4x-15 3x-4x=-15-32 x=-47
the equation of that would be 4x-5 if that's what your looking for
4n - 10 = 38 (add 10 to both sides)4n = 48 (divide by 4 to both sides)n = 12
48-n=4n-7
X = number 48 - X = 4X - 7
As the subtraction is done first, it needs to be in brackets; thus eighteen decreased by four then times three is: (18 - 4) × 3
The answer is: 2 or -2
n (number) minus four ----->n-4

x-(x+4)
