Step-by-step explanation:

Given 2x+3y+8 = 0 ...(1)

      4x+5y+14 = 0 ...(2)

multiply equation. (1) by 5 and equation (2) by 3 we get

10x + 15y + 40 = 0 

12x + 15y + 42 = 0

      -      -         -

___________________

-2x-2=0

[x = -1] from equation.(1)   3y = 8 -2x

y=310

Hence using cross multiplication method intersection point of line 1 & 2 are(−1,310)
