Question

2x+3y=1 ,3x-y=7 solve using elimination method​

Answer 1

hi

Answer:

x= 2

y= -1

Step-by-step explanation:

2x + 3y = 1 ---------(1)

3x - y = 7 -------------(2)

now,

(2) × 3 = 9x - 3y = 21----------(3)

now, addition

(3) = 9x - 3y = 21

(1) = 2x + 3y = 1

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

11x = 22

x = 2

substituting this value in eq 1

2 × 2 + 3y = 1

4+3y=1

y= -1
