2(4x+10)=8x+k

An equation with infinitely many solutions is a function which has after try to find the solution an result as (0 = 0)

Then, for the given equation:

1. Remove parenthesis by multiplying 2 by the two term in parenthesis:


8x+20=8x+k

2. The value that makes the equation have many solutions is 20 because:


\begin{gathered} 8x+20=8x+20 \\ 8x-8x=20-20 \\ 0=0 \end{gathered}Answer B)20
