Can someone please help me

The area of Europe is about 3 million square miles less than the area of South America. The area of Europe is about 4 million square miles. Write an equation with these quantities. Use s for the area of South America, in millions of square miles.

S =7

equations:  E = 4  and

E = S - 3

Step-by-step explanation:

Let area of Europe = E

Let area of South America = S

then

E = 4

E = S - 3

then  S = E + 3 = 4 + 3 = 7

So  S = 7
