$ The sum of twe numbers is 42. Their difference is 16.

tresset_1 [31]

Answer:

x = 29

y = 13

Step-by-step explanation:

Write 2 equations:

x + y = 42

x - y = 16

Isolate x in the first equation:

x = 42 - y

Substitute this in for x in the second equation:

42 - y - y = 16

42 - 2y = 16

solve for y:

-2y = -26

y = 13

Plug in 13 for y in either equation:

x + 13 = 42

Solve for x:

x = 29
