Answer 2

Answer:

Step-by-step explanation:

SOLUTION:

Given pair of Linear Equations are:

3x - 4y +3 =0 ……………….(1)

3x + 4y - 21 = 0 …………….(2)

Put x= 3 in eq 1

3x - 4y +3 =0

3×3 - 4y +3= 0

9 - 4y = - 3

9 +3 = 4y

12 = 4y

y = 12/4= 3

A(3, 3)

Put y= 0 in eq 1

3x - 4 × 0 = -3

3x = -3

x =- 3/3 = -1

B(-1,0)

Put x= 3 in eq 2

3x + 4y -21 =0

3×3 + 4y = 21

9 + 4y = 21

4y = 21 -9

4y = 12

y = 12/4= 3

A(3, 3)

Put y= 0 in eq 2

3x + 4×0= 21

3x + 0 = 21

3x = 21

x = 21/3

x = 7

x = 2
