Question

Solve the following pair of equations graphically.
2x – 3y = 1
1.25x + 0.5y = 3

Answer 1

Answer:

put the values of x=0,1,2,3,4 so on

and you will get the respective values of y

and now plot a graph using values of x and y

finally join all points.

Answer 2

Answer:

Step-by-step explanation:

2x + 3y = 1

therefore,

               x = (3y + 1)/2       ---------------------(1)

1.25x + 0.5y = 3

(125/100)x + (5/10)y = 3

(125/100)x + (50/100)y= 3

therefore,

                 125x + 50y = 300    -------------------(2)

divide b.s by 5

25x + 10y = 60

{25(3y + 1)/2} + 10y = 60

(75y + 25)/2 + 10y = 60

[(75y + 25) + (10y*2)]/2 = 60

75y + 25 + 20y= 120

95y = 145

y = 145/95

y= 1.52

there by putting valur of y in (1)

x= -1.78
