Step-by-step explanation:
hope this will help you
Step-by-step explanation:
6x-3y=-10,3x +5y-8=0
a1 = 6 , b1 = –3 , c1 = –10
a2= 3 ,b2 =5 , c2 = 8
D = a1. b1. = 6 –3 = 6×5 –( –3×3)
a2. b2. 3. 5. 30 – (–9)
30+9
39
Dx = c1. b1. = –10 –3 = –10×5 – 8×–3
c2. b2 8 5 –50 – (–24)
–50 + 24
–26
Dy = a1. c1 = 6 –10 = 6×8 – 3×–10
a2. c2 3. 8. 48 – (–30)
48+30
78
By Cramer method
x = Dx/D
–26 /39
–2/3
y = Dy/D
78/39
6/3
2/1
2
(x,y) = (–2/3 , 2) is the solution of given equation.
