il corte in and 5 pensa​

Answer 1

Step-by-step explanation:

x + y =9 ----(1)

3x +2y = 22 ------(2)

Dividing equation (1) by 2

2x+2y = 18 -------(3)

Substrct equation (2) and (3)

3x+2y =22 ----(2)

2x+2y = 18------(3)

-----------------

5x. = 40

x= 40/2

x = 8

Put x =8 in equation (1)

x + y = 9

8+ y = 9

y = 9-8

y = 1

(x, y) = (8, 1 ) is the solution
