Question

The sum of two numbers is 35. Four times the the first number minus the second number is 10. What Are the two numbers?

( First number, Second number)

Answer 1

9, 26

Explanation:

x = 1st number

y = 2nd number

x + y = 35 → y = 35 - x

4x - y = 10 substitute y = 35 - x into this equation and solve for x

4x - (35 - x) = 10

4x - 35 + x = 10

5x = 10 + 35

5x = 45

x = 45/5 = 9

Now you can solve for y:

y = 35 - x = 35 - 9 = 26

Answer 2

Explanation:

Let the first no be x

Second number woud be 35-x

So , second equation would be

4*x - (35-x) = 10

5x-35 = 10

5x = 45

x=9

Second number is 35-9 = 26
