Answer:
x=3, y= -1
Step-by-step explanation:
The given equations may be written as: 2x + 5y – 1 = 0 …….
(i) 2x + 3y – 3 = 0 …….
(ii) Here a1 = 2, b1 = 5, c1 = -1, a2 = 2, b2 = 3 and c2 = -3
Using cross multiplication method.
x/(-15+3)=y/(-2+6)=1/(6-10)
x/(-12)=y/(4)=1/(-4)
x/12=1/-4 ➡️ x= (-12/-4)=3
y/4=1/-4 ➡️ x=(4/-4) =-1
