Question

The sum of two numbers is 70 . The first number is 2/5 of the second number

Answer 1

Question:

Solution:

Let x represent the first number and y represent the second number, according to the problem, we get the following two equations:

Equation 1: the sum of two numbers is 70:

`x+y=70`

and

Equation 2: The first number is 2/5 of the second number :

`\text{x = }(2)/(5)y`

Then, we can conclude that the correct system of equations that represent the problem is:

`x+y=70`

`\text{x = }(2)/(5)y`
