Question

निम्न समीकरण युग्म को ग्राफिय विधि से हल कीजिए। 4x - 7y + 28 = 0 8x - 14y - 30 = 0 ka ansr

Answer 1

Answer:

49x+16x+40−105=0

65x=65⇒x=1

From eq (1)

4−7y=−10

−7y=−14

y=2

Answer 2

Given: 4x - 7y + 28 = 0

8x - 14y - 30 = 0

To Find : समीकरण युग्म को ग्राफिय विधि से हल कीजिए।

Solution:

4x - 7y + 28 = 0

x = 0  => y =  4

y = 0  => x = - 7

(-7 , 0)  and ( 0 , 4)  

Draw line passing through points

8x - 14y - 30 = 0

x = 2 => y  = - 1

x = -5  => y = -5

(2 , -1)  and ( -5 , -5)  

Draw line passing through points

Both lines are parallels

Hence , No solution
