Given equation:
[tex]4x+y=8[/tex]In order to find equavalent equation of the given one , we have to divide or multiply any number to both sides of the equation
In this case , I'm multiplying the equaiton with 2
So, mutiplying each term with 2
[tex]\begin{gathered} (4x\times2)+(y\times2)=8\times2 \\ 8x+2y=16 \end{gathered}[/tex]Hence, one equivalent equation of the given equation is
[tex]8x+2y=16[/tex]
