7x+2y=4 and -5x-3y=5−5x−3y=5

one solution : (2 , - 5)

Step-by-step explanation:

hello :

the system is :   7x+2y=4 ...(*)

                        -5x-3y=5(**)

multiply (*) by 3 and (**) by 2 you have :  21x+6y =12(1)

                                                                  -10x-6y =10(2)

add(1) and (2) : 11x=22  so x= 2

put this value in (2) : -20-6y =10

-6y=30 so y = -5

one solution : (2 , - 5)

.27

Step-by-step explanation:
