Question

Solve the given pair of linear equations:
2x +3y =6
x +y = 8​

Answer 1

Answer:

2x + 3y = 6 .....(i)

x + y = 8......(ii)

multiplying equation (ii) with 2 and subtract both the equation

2x + 3y = 6

2x + 2y = 16

- - -

y = -10

now from equation (ii)

x+ (-10) =8

x -10 =8

x =8+10

x =18

hence x= 18 & y =-10
