Answer:
y = 9
x = 22
Step-by-step explanation:
Let the larger integer = x
the smaller integer = y
The following equations can be derived from the question
x + y = 31 --equation 1
x = 4 + 2y --equation 2
Substitute for x in equation 1
4 + 2y + y = 31
solve for y
3y = 27
y = 9
substitute for y in equation 1 and solve for x
x = 31 - 9 = 22
y = 9
x = 22
