RS Aggarwal Solutions Class 10 Chapter 3 Linear equations in two variables Ex 3C

Question 1:
x + 2y + 1 = 0 —(1)
2x – 3y – 12 = 0 —(2)
By cross multiplication, we have

Hence, x = 3 and y = -2 is the solution
Question 2:
2x + 5y – 1 = 0 —(1)
2x + 3y – 3 = 0 —(2)
By cross multiplication we have

Hence the solution is x = 3, y = -1
Question 3:
3x – 2y + 3 = 0
4x + 3y – 47 = 0
By cross multiplication we have

Hence the solution is x = 5, y = 9
Question 4:
6x – 5y – 16 = 0
7x – 13y + 10 = 0
By cross multiplication we have

Hence the solution is x = 6, y = 4
Question 5:
3x + 2y + 25 = 0
2x + y + 10 = 0
By cross multiplication, we have

Hence the solution is x = 5, y = -20
Question 6:
2x + y – 35 = 0
3x + 4y – 65 = 0
By cross multiplication, we have

Question 7:
7x – 2y – 3 = 0
By cross multiplication, we have

Hence x = 1, y = 2 is the solution
Question 8:

Question 9:
ax + by – (a – b) = 0
bx – ay – (a + b) = 0
By cross multiplication, we have

Question 10:
2ax + 3by – (a + 2b) = 0
3ax + 2by – (2a + b) = 0
By cross multiplication, we have

Question 11:

By cross multiplication, we have
