The sum of two numbers is 56. The larger exceeds twice the smaller by 2. Find the numbers.
I already tried x+2+2y = 56 with the substitution of x= 56-y

Good effort...I think you made the wrong substitution or equation

Step 1. Let x be the smaller integer and y be the larger integer.

Step 2. Then y=2x+2 since the larger exceeds twice the smaller by 2.

Step 3. x+y=56 or x=56-y

Step 4. Then substituting x=56-y%29 into y=2x%2B2 yields the following

y=2%2856-y%29%2B2

y=112-2y%2B2

y=114-2y

Add 2y to both sides

y%2B2y=114-2y%2B2y

3y=114

Divide by 3 to both sides of the equation

3y%2F3=114%2F3

y=38

and x=56-y=56-38=18

Check equation if true in Step 2... 2*x+2=2*18+2=38...which is a true statement.

Step 5. ANSWER: The numbers are 18 and 38.

I hope the above steps were helpful.

x+y=56 or x=56-y
y=2x+2
y=2(56-y)+2
y=112-2y+2
y+2y=112+2
3y=114
y=114/3
y=38 ans.
x+38=56
x=56-38
x=18 ans.
Proof:
38+18=56
56=56
