Question

34. Find the Solution to the given pair of linear equations by graphical method.
x + y = 5
2x - y = 4​

Answer 1

Answer:

x=3, y=2

Step-by-step explanation:

x+y= 5

2x-y= 4

3x+0=9

$\frac{3x}{3}$ = $\frac{9}{3}$

Three into 3 goes 1 time, three into three goes 1 time and three into 9 goes 3 times

x=3

x+y= 5

3+y=5

y=5-3

y=2

Therefore, if x=3 then y=2

Answer 2

Answer :

x = 3 , y = 2

Step by step explanation

x + y = 5

2x - y = 4

by adding

x + y = 5

2x - y = 4

________

3x =9

x = 9 ÷ 3

x = 3

put x = 3

x + y = 5

3 + y = 5

y = 5 - 3

y = 2

(x , y) = (3 , 2)
