Question

find the value of determinants in the given equation 3 X - 2 y is equal to 3 and 2 X +y is equal to 16​

Answer 1

Answer:

x= 5 , y= 6

Step-by-step explanation:

3x-2y=3....(1)

2x+y=16....(2)

Multiplying eq (2) by 2 ,

4x+2y= 32...(3)

Adding (1) and (3) ,

3x-2y=3

+ 4x+2y=32

__________

7x = 35

so, x = 35÷7

x= 5

Substituting x=5 in eq(1) ,

3x-2y=3

(3×5) - 2y=3

15- 2y = 3

-2y= 3 - 15

-2y= -12

y= 12÷2

so, y= 6
