solve graphical x-2y=5 2x+y=5
Answers
Answer:
now u can draw the graph but pls not there's one mistake there's a fraction so if there's a fraction when u find the value u cannot draw a graph so over there pls put some other value.think and do it.
Hope it helps u
pls mark me branliest
EXPLANATION.
Graphically equation.
⇒ x - 2y = 5 and 2x + y = 5.
As we know that,
From equation (1), we get.
⇒ x - 2y = 5.
Put the value of x = 0 in equation, we get.
⇒ (0) - 2y = 5.
⇒ - 2y = 5.
⇒ 2y = - 5.
⇒ y = -5/2.
⇒ y = -2.5.
Their Co-ordinates = (0,-2.5).
Put the value of y = 0 in equation, we get.
⇒ x - 2(0) = 5.
⇒ x = 5.
Their Co-ordinates = (5,0).
From equation (2), we get.
⇒ 2x + y = 5.
Put the value of x = 0 in equation, we get.
⇒ 2(0) + y = 5.
⇒ y = 5.
Their Co-ordinates = (0,5).
Put the value of y = 0 in equation, we get.
⇒ 2x + (0) = 5.
⇒ 2x = 5.
⇒ x = 5/2.
⇒ x = 2.5.
Their Co-ordinates = (2.5,0).
Both curves intersects at a point = (3,-1).
