Answer:
6
Step-by-step explanation:
Let the first number be x
Let the second number be y
x + 2y= 4............equation 1
2x +y= 11............equation 2
From equation 1
x + 2y= 4
x = 4-2y
Substitute 4-2y for x in equation 2
2x + y= 11
2(4-2y) + y= 11
8-4y+y= 11
8-3y= 11
-3y= 11-8
-3y= 3
y= -1
Substitute -1 for y in equation 1
x + 2y= 4
x + 2(-1) = 4
x-2= 4
x = 4+2
x = 6
Hence the first number is 6
