We are looking for the value of 2 integers, so let's call them x and y (where y is the larger integer). First we need to write the question out as an expression:
4%28x%2By%29=2%2B14y
Expand the brackets:
4x%2B4y=2%2B14y
Subtract 4y from both sides:
4x+=+2+%2B10y
Now, if they are consecutive integers, we know that:
x+=+y-1
If we substitute this into the previous equation, we get:
4%28y-1%29+=+2%2B10y
Expand the brackets:
4y+-+4+=+2%2B10y
Add 4 to both sides:
4y+=+6+%2B+10y
Subtract 10y from both sides:
-6y+=+6
Divide both sides by -6:
y+=+-1
Since x is one less than y:
x=-2
The 2 integers are -2 and -1.
