Question

X/5 +x/15 =2/5 X/5 +x/15=2/5

Answer 1

3x+x=10

4x= -10

x= -5/2

x= -2 1/2

Answer 2

3 x + x = 6

4 x = 6

$x = \frac{3}{2}$

Answer 3

To solve the equation (X/5) + (X/15) = 2/5, we need to find the value of X that satisfies the equation.

First, let's find a common denominator for the fractions on the left-hand side of the equation, which is 15.

Multiplying the first fraction (X/5) by 3/3 to get a denominator of 15, we have (3X/15).

The equation now becomes: (3X/15) + (X/15) = 2/5.

Combining the fractions with the same denominator, we have: (3X + X) / 15 = 2/5.

Now, let's cross-multiply to eliminate the fractions.

(3X + X) * 5 = 2 * 15.

15X + 5X = 30.

Combining like terms, we have: 20X = 30.

To isolate X, we divide both sides of the equation by 20:

X = 30/20.

Simplifying the fraction, we have: X = 3/2 or X = 1.5.

Therefore, the value of X that satisfies the equation is 1.5.
