Right Answer is:
SOLUTION
Let us assume, x and y are the two numbers and
x > y
Given:
x + y = 80 -----------(1)
Also
given:
x =2y + 11 --------------(2)
Substitute
the value of x from equation 1 in equation 2
2y + 11 + y = 80
3y+ 11 = 80
3y= 69
y =
23
Therefore,
x = 2y + 11 = (2 * 23) + 11 = 57
The
two numbers are 57 and 23
