Question

solve the following pair of
linear equation
by elimination
method

x/5-y/3=4/15
x/2-y/9=7/18​

Answer 1

Step-by-step explanation:

x/5-y/3=4/15

3x-5y =4/15

15

3x-5y=4/15 X 15

3x-5y=4________(1)

x/2-y/9=7/18

9x-2y =7/18

18

9x-2y=7/18 X 18

9x-2y=7_______(2)

by multiplying equation (1) by 3

3(3x-5y)=4 X 3

9x-15y=12

by subtracting equation (1) and (2) we get

9x-15y=12

- 9x-2y =7

-17y=5

y=5/-17

by putting the value of y in eq (1)

3x-5x5/-17=4

3x-25/-17=4

3x=4+25/-17

3x=68+25

-17

3x=93/-17

x=93/-17 ÷3

x=93/-51

I hope this will help you
