Question

Solve it with elimination method.....

Answer 1

Answer:

3x- 2y= 5 ----------1

6x- 4y= 10 ----------2

Solving by elimination method

Multipliying 2 with eq. 1 and 1 with eq. 2

2( 3x- 2y )= 5× 2

6x- 4y= 10

6x- 4y= 10

0= 0

hence, the equation has infinite many solution

Note- There are many cases in which the equation has no variable if the statement is true then it has infinite many solution. if it is false then it has no solution.

ii) 7x+ y= 3

- 14x- 2= 2

Assuming 2 = y in eq 2 as it is incoorect

7x+ y= 3

(-14)x - y= 2

Multipliying 2 with eq. 1 and 1 with eq. 2

2(7x+ y)= 3× 2

(-14x- y)= 2

14x+ 2y= 6

-14x- y= 2

3y= 8

y= 8

x= 3-y/7

Putting value of x in eq. 1

X= 3-8/7

x =(-5/7)
