Answer: x = 15, y = 5

Step-by-step explanation:

The given system is [tex]x+y=20.........................(1)//3x-3y+30...............................(2) [/tex]

Multiplying 3 on both sides of equation (1), we get

[tex]3x+3y=60.........................(3)[/tex]

Now, adding (2) and (3), we get

[tex]6x=90\\\\\Rightarrow\ x=15[/tex]

Substitute the value of x in (1), we get

[tex]15+y=20\\\\\Rightarrow\ y=20-15\\\\\Rightarrow\ y=5[/tex]

Hence, the of x and y satisfy this system of equations is x = 15, y = 5.

Answer:

The answer is : X=15,Y=5
