Answers
Answer:
x=4 and y=3
Step-by-step explanation:
Given : Equation and
To find : Solve the system of equation by method of cross multiplication?
Solution :
Let Coefficient of x - A
Coefficient of y - B
Constant term - C
Method of cross multiplication is
x y -1
B C C A A B
3 -17 -17 2 2 3
-2 -6 -6 3 3 -2
Cross multiply,
x y -1
(-18-(34)) (-51-(-12)) (-4-9)
(-52) (39) (-13)
Comparing x , i.e.
Comparing y , i.e.
Therefore, The value of x is 4 and the value of y is 3.
