Question

solve for x and what is the root?

square root of 3x+1=7

Answer 1

\[\sqrt{3x+1}=7\] square both sides and solve
\[3x+1=49\] in two steps

Answer 2

oh, if it is
\[\sqrt{3x}+1=7\] then subtract 1 from both sides and get
\[\sqrt{3x}=6\] then square both sides to get
\[3x=36\] and solve in one step
