Answer 1

Answer:

do u want to say by crammers method.

Ok ¡

I am solving by crammers method

3x + 5y = 12

6x - 5y = 6

3 5

D = = [(3× 5) - 5 × (-5)]

6 -5

= (-15) - 30

D = - 45

D(x) = 12 5

= [12 × (-5)] -(6 × 5)

6 -5

= (-60) - 3

D(x) = - 90

D(y) = 3 12

= (3 × 6) - (12 × 6)

6 6

= 18 - 72

D(y) = - 54

Now , finding the value of x and y

x = D(x) / D

= -90 / -45

x = 2

y = D(y) / D

= - 54 / -45

y = 1.2

Ans. (x,y) = (2, 1.2) is the solution of the above equation.

Note: I didn't written the formula, for formula see in ur Text book.
