Question

whats the answer to 2/3y- 2/5 =5

Answer 1

2/3y- 2/5 =5

add 2/5 on both sides:

2/3y = 5 + 2/5

Combine the fraction:

2/3y = 5 2/5

Write in improper Fraction:

2/3y = 27/5

Divide both sides by 2/3:

y = 27/5 ÷ 2/3

Change divide fraction to multiplication fraction:

y = 27/5 x 3/2

y = 81/10

Write in mixed number:

y = 8 1/10

Answer: y = 8 1/10

Answer 2

From the above details, we can take 2/3y - 2/5 = 5.

It is important to find out the LCM of the numbers.

The LCM becomes 15. We need to substitute the value on the given equation.  

The calculation for this given equation is explained below.  

10y - 6 upon 15= 5

10y - 6 = 75

10y = 81

y = 8.1
