Question

What is the solution to sqrt(1-4x)=3?

Answer 1

\[\sqrt{1-4x}=3\] first you got to get rid of that square root by squaring everything
1-4x=9
minus 1
-4x=8
divide by -4
x=-2
substitute to see if it works

Answer 2

yes it worked,thank you so much :)

Answer 3

\[\sqrt{1-4x}=3\]
taking square on both sides
now it becomes
1-4x=9
1-9=4x
-8\4=x
x=-2
now for verification put x=-2 in the given equation
\[\sqrt{1-4(-2)}\]
\[\sqrt{1+8}=3\]
\[\sqrt{9}=3\]
3=3
hence shown
