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
