Question

8 x + 5 Y is equal to 11 and X + Y is equal to 4 find the value of variables by elimination method​

Answer 1

Step-by-step explanation:

8x+5y=11(1)

x+y=4(2)

multiplying both sides by 5 of(2)

5x+5y=20(3)

subtracting (3) from (1)

8x+5y-5x-5y=11-20

3x=-9

x=-3

put value of x in y

8×-3+5y=11

-24+5y=11

5y=35

y=7

Answer 2

Answer:

8x+5y= 11 ---------1

x+y= 4. ----------2*5

-----------------

8x+5y = 11

40x+5y= 20

- - -

--------------------

-32x=-9

x=-9/-32

=9/32

so,

8x+5y=11

8(9/32)+5y=11

9/4+5y=11

9+5y=44

5y=44-9

5y=35

y=35/5

=7.
