find x or y so that the statement is true 2 a 3x1272 b C PAS

find x or y so that the statement is true:

2. (a) (3x+1,2)=(7,2)

    (b) (C++, PASCAL) = (y, x)

4. (a) (x2,25) = (49, y)           

    (b) (x, y) = (x2, y2)

6. let A = {a,b} and B = {4,5,6}

List the elements in

(a) A

Solution

6. let A = {a,b} and B = {4,5,6}

List the elements in

(a) A
