As given by the question,
There are given that the equation:
[tex]4x+2y=20[/tex]Now,
First, suppose any number, for which the given equation has satisfied.
So, the number is, x = 2 and y = 6
Then,
Put both values into the given equation
[tex]\begin{gathered} 4x+2y=20 \\ 4(2)+2(6)=20 \\ 8+12=20 \\ 20=20 \end{gathered}[/tex]Then,
Put the same value of x and y into the given option and check whether it is satisfied:
So,
From option 3:
[tex]\begin{gathered} 2x+y=10 \\ 2(2)+6=10 \\ 4+6=10 \\ 10=10 \end{gathered}[/tex]Hence, the correct option is 3.
