Answer 2

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
