Question

solve graphically the pair of liner equation 5x-y=5 and 3x-y=3​

Answer 1

Given pair of Linear Equations are:

5x - y =5  ……………….(1)

3x - 2y = - 4 …………….(2)

Put x= 0 in eq 1

5x - y =5

5×0 - y = 5

0 -y = 5

y = - 5

(0,-5)

Put y= 0 in eq 1

5x - 0 = 5

5x = 5

x = 5/5 =1

(1,0)

Put x= 0 in eq 2

3x - 2y = - 4

3×0 -2y = -4

0 -2y = -4

2y = 4

y = 4/2 = 2

(0,2)

Put y= 5 in eq 2

3x - 2×5= -4

3x -10  = -4

3x = - 4 +10

3x = 6

x = 6/3 = 2

x = 2

(2,5)
