Question

x/7+Y/3=5
x/2- y/9=6
solve this equation by cross multiplication method
this question belongs to class 10th in linear equation in two variables chapter

Answer 1

x/7+y/3=5 equation (1)

x/2-y/9=6 equation (2)

x/7+y/3 =5 add

3x+7y=105 equation( 1)

x/2-y/9=6 add

9x-2y=108 equation (2)

3x+7y=105 multiply by 2

9x-2y=108multiply by 7

6x+14y=210

63x-14y=756

69x=966

x=14

6×14+14y=210

84+14y=210

14y=210-84

14y=126

y=9

so x=14

y=9
