Answer 1

Answer:

Step-by-step explanation:

x=-29

Answer 2

Answer:

2x+3y=19------------Eq 1

7x+9y=29​-----------Eq 2

From eq 1 we get,

x = (19 - 3y)/2

Put this value of x in eq 2 ,

7(19 - 3y)/2 +9y=29

By solving this we will get the value of y ,

Then substitute the value of y in eq 1 to find x.
