Question

Dos números que suman 54 pero tienen una diferencia de 30

Answer 1

12 y 42

Explanation:

Let x and y represent the two numbers:

(1) x+y=54 and (2) x-y=30

Solve for x:

x-y=30

x=30-y

Substitute into equation (1):

(30-y)+y=54

2y+30=54

2y=24

y=12

Substitute into equation (2):

x-12=30

x=42
