Let the missing integer be x.

Now,

4(28) = 4(20) + 4(x)

According to distributive property,

A(B+C) = AB + AC

Substituting dsitributive property into the equation, we get,

4(28) = 4(20) + 4(28 - 20)

4(28) = 4(20) + 4(8)

Thus, the missing integer is 8.

(Check it!)

4(28) = 4(20) + 4(8)

112 = 80 + 32
112 = 112 ;

or, LHS = RHS.
Hence proved.
