Question

two numbers that sum 13 and the difference is 5

Answer 1

Answer:

x + y = 13

And

x - y = 5

Add both the equation

2x = 18

x = 9

And,

y = 13 - 9 = 4

Answer 2

Answer:

9 and 4

Step-by-step explanation:

Let the two numbers be a and b.

a > b

a + b = 13 -------> eq 1.

a -  b  = 5

_______ +

2a +0 = 18

2a = 18

a = 18 / 2

a = 9

Substitute a = 9 in eq 1,

9 + b = 13

b = 13 - 9

b = 4

The two numbers are 9 and 4.
