$\huge\tt\red{A}\tt\pink{N}\tt\blue{S}\tt\green{W}\tt\purple{E}\tt\orange{R}$☘

Step-by-step explanation:

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

Then 1/2+3/2

Taking l. C. M both side

L. C. M. =2

Then

4/2
