Question

(ii) 2x+y=5
3x +2y=8
(iv) x - 3y - 7= 0
3x - 3y - 15=0
does the following pair of linear​

Answer 1

Answer:

(ii) 2x+y=5 , 3x+2y = 8 (is a linear equation )

(iv) x - 3y - 7= 0 , 3x - 3y - 15=0(is a Linear equation )

Step-by-step explanation:

(ii) =8

you can solve this by eliminating y

2x+y=5

3x+2y= 8

multiplying 2 in equation 2x+y=5

(2x+y=5 ) × 2

3x+2y= 8

now substraction of both the equation we get

4x+2y=10

- 3x+2y=8

________

x= 2

putting value of x in equation 3x+2y = 8 we get

3×2+2y=8

2y=2

y=1

hence the following pair of the equation 2x+y=5

3x+2y= 8 is a linear equation
