plz answer the question
it's very urgent
I'll make u brain list..​

Answer 1

Answer:

5x+7y=50___(1)

7x+5y=46___(2)

for equation (1)

we can write,

x=(50-7y)/5

from this,

x 3 10 -4

y 5 0 10

similarly for equation (2)

x=(46-5y)/7

from this,

x 8 3 -2

y -2 5 12

from these we can take graphical representation,

for this please check attachment

(note: draw it on graph paper for better result)

from graphical representation we can say;

x=3 and y=5
