Answer:
One is 89 , the other is 33.
Step-by-step explanation:
Set up a system of 2 equations:
x + y = 122
x - 2y = 23 Subtracting:
0 + 3y = 99
y = 33.
So:
x + 33 = 122
x = 122 -33 = 89.
Answer:
first number= 89 and second number= 33
Step-by-step explanation:
here, let the first number be X and the second number be y,then
From the question,
x + y = 122 ---- eq i
x -2y = 23 ----- eq ii
From substitution method,
From eq i,
x + y = 122
or, x =122 - y
Now, putting the vale of x in eq ii,we get,
122 -y -2y = 23
or, -3y = 23-122
or, -3y = -99 (cut minus sign in both sides)
or, y=99/3
or, y = 33
Again, putting the value of y in eq i,we get,
x + 33 = 122
or, x= 122-33
or, x=89
