Question

X2 + xy -3x = 2
5y + 6y = 22

Answer 1

Answer:

x=-1 and 2

y=2

Step-by-step explanation:

5y+6y=22

or,11y=22

or,y=2

now,

putting in 1st equation ,

x^2 +xy -3x=2

or, x^2 +2x-3x=2

or, x^2-x=2

or,x^2-x-2=0

or,x^2-2x+x-2=0

or,x(x-2)+1(x-2)=0

or,(x+1)(x-2)=0

either,(x+1)=0 i.e. x=-1

or,x-2=0 i.e x=2

Answer 2

Answer:

y= 2

x= 2 or (-1).

Hope you understand this solution of mine.

Thank you
