Question

35. Solve graphically. 5x+y=7
x+y=1​

Answer 1

Step-by-step explanation:

first we put any value i put there x value 1

Answer 2

Step-by-step explanation:

In equation 5x + y = 7

putting value of x = 0

5(0) + y = 7

0 + y = 7

y = 7

(0 , 7)

putting value of x = 1

5(1) + y = 7

5 + y = 7

y = 7 - 5

y = 2

(1 , 2)

putting value of x = 2

5(2) + y = 7

10 + y = 7

y = -3

(2 , -3)

In equation x + y = 1

putting value of x = 0

0 + y = 1

y = 1

(0 , 1)

putting value of x = 1

1 + y = 1

y = 0

(1 , 0)

putting value of x = 2

2 + y = 1

y = 1 - 2

y = -1

(2 , -1)

by putting all these points on graph you will get solution of the equation

The point of intersection of two lines is (1.5 , 0.5)

So the solution of this equation is

X = 1.5

Y = 0.5

Hope this will help you
