Step-by-step explanation:
3x + 5y = 9 and 5x + 3y = 7
By doing substitution method
3x=9–5y
X=(9–5y)/3
Putting this value in equation 2 then we get
5(9–5y)/3+3y=7
45-25y+9y=21
45–21=25y-9y
24=16y
Y=24/16
Putting value of y in equation 1 then we get
3x+5*24/16=9
3x=9–15/2
3x=(18–15)2
X=1/2
So our answer is
X=1/2and y=24/16 =3/2
