(3/10) x - 2 = (1/5) x
3x. - 20 = 2x
x = 20 _______is the number
Let the number be n and so if 3/10n -2 = 1/5n then the value of n is 20
Let x be the number.
3x/10 - 2 = x/5
3x - 20 = 2x
x = 20
When 2 is subtracted from three-tenths of a number,
(3x/10) - 2
the result is equal to one-fifth of a number.
(3x/10) - 2 = x/5
Multiply both sides by 10 to get rid of fractions:
3/10 n - 2 = 1/5 n
3n - 20 = 2n
n = 20
The number is 20.
(0.3)x – 2 = (1/5)x
3x – 20 = 2x
check
3/10 of 20 = 6
6-2 = 4
(1/5)20 = 4
ok
