Answer 1

Answer:

Hey guys

Step-by-step explanation:

first n large number= x

second n small number = y

The sum of two numbers is 87

x+y=87 _______________- eq 1

twice the smaller number=2y

subtracted from the larger number, the result is 12

x -2y = 12 _______________ eq 2

subtract eq 2 from eq 1

x+y=87

-x+2y=-12

_____________

3y=75

y=25

substitute y=25 in eq 1

x+y=87

x+25=87

x=62

first n large number= x=62

second n small number = y=25
