Question

The sum of a number and its two third is 15.Find the number.​

Answer 1

Answer:

6

Step-by-step explanation:

x + y = 15

y = 2/3x, therefore  

x + (2/3x) = 15

Step 1: Simplify both sides of the equation.

(x+2/3x) = 15 (Combine Like Terms)

5/3x=15

Step 2: Multiply both sides by 3/5

(3/5) ⋅ (5/3x) = (3/5) ⋅ (15)

Therefore ...  x = 9

Remember that y = 2/3x?

So, y = (2/3) ⋅ 9 = 6
