Question

from the sum of 3x-y+11 and -y-11 subtract 5x-2y+11​

Answer 1

3x - 4y = 15. ---(1)

5x - 2y = 11-----(2)

multiply equation (1) by 5 and equation (2) by 3

we get ,

15x - 20y = 75

15x - 6 y = 33

____________ by subtracting it !

-14 y = 42

y = -3

now put the value of. " y" in equation (1)

3 x - 4 (-3 ) = 15

3x = 15 - 12

3x = 3

x = 1

hence ,the value of "x " and "y " are 1 and -3.
