Answer:

I can't tell answer plzz iam not able to understand that

Answer 2

Answer:

11x+15y =-23

7x-2y=20

Step-by-step explanation:

x=2 ,y= -3

i think u know the elimination method to solve the 2variable equation i can help u to solve in the first equation u multipy 2in whole u get 22x+30y= -46 and in second u multiply 15in whole u get 105x-30y=300 in this way the y variable cut and u have left only one variable

hope u understand
