Nadia has 20 more postcards then pete. after nadia gives pete some cards pete has 2 more postcards than nadia. how many postcards does nadia give to pete?

11 postcards.

Step-by-step explanation:  

Let x be the number of postcards that Pete have. Let y be number of postcards that Nadia gave to Pete.

Let us solve for x.

Add y to both sides of equation.

Subtract x from both sides of equation.

Therefore, Nadia gave 11 postcards to Pete.
