Question

the sum of 2 number is 64,twice the large number plus five times the smaller number is 20 find the 2 numbers​

Answer 1

The two numbers are: - 36 and 100

Explanation:

let the smaller number = x, let the larger number = y

then...

x + y = 64

5x + 2y = 20

use substitution: y = (64 - x)

5x + 2(64 - x) = 20

3x = 20 - 128 = - 108

x = - 36

So the two numbers are: - 36 and 100
