1/2x - 1/5x = 3?

Question

Is it x = .1 ?

Answer 1

1/20 - 1/50 does not equal 3. Try again.

1/2x - 1/5x = 3
3/10x = 3
x = 10

Answer 2

1/2x - 1/5x = 3?
From the way you have written the problem, x seems to be the denominator, & hence,
The Lowest Common Multiple of 2x & 5x = 10x
(5-2)/10x= 3
3 / 10x = 3
30x = 3
x = 3/30 = 1/10 = 0.1
================
If the 'x' is a part of the numerator, it is to be written as:
(1/2)x - (1/5)x = 3
x/2 - x/5 = 3
(5x - 2x) / 10 = 3
3x / 10 = 3
3x = 3 * 10 = 30
x = 30 / 3 = 10
============

Answer 3

No, to solve the equation multiply both sides of the equation by 10

10(1/2X - 1/5X = 10(3) or

5X - 2X = 30 therefore

3x = 30 then divide by 3 and come up with

X = 10

Answer 4

1/2x-1/5x=3
Least common denominator is 10: So
10(1/2x-1/5x=3)
5x-2x=30
3x=30
x=10

Proof (1/2) (10) -(1/5) (10) =3
5-2=3

Answer 5

(1/2)x - (1/5)x = 3

(5x - 2x)/10 = 3

3x/10 = 3

x = 3(10/3)

x = 10

Answer 6

An equation like this could truthfully be broken down right into a, b, and c, in case you turn it into an f(x) = 3x - 3 = 2x - 10x^2 f(x) = 10x^2 + x - 3 And so: a = 10 b = one million c = -3 Chow!

Answer 7

Do you mean
1x/2-1x/5=3
5x/10-2x/10=3
3x/10=3
3x=30
x=10
or

1/2x-1/5x=3
5-2=30x
30x=3
x=1/10


Hope that helps!

Answer 8

(1/2)x - (1/5)x = 3
(3/10)x = 3
x = 10

plug it back in to see if it works

(1/2)(10) - (1/5)(10) = 3
5 - 2 = 3
3 = 3

Answer 9

(1/2)x - (1/5)x = 3
5x - 2x = 30
3x = 30
x = 10

Answer 10

(1/2)x-(1/5)x=3
(5/10)x-(2/10)x=3
(3/10)x=3
x=10
