Question

what is the solution to √1 - 4x = 3?

Answer 1

\[\sqrt{1-4x}=3\]

Answer 2

\[\sqrt{1-4x}\color{red} {^2}=3\color{red} {^2}\]\[1-4x=9\]\[1-4x\color{red} {-1}=9\color{red} {-1}\]\[-4x=8\]\[-4x\color{red} {\div (-4)}=8\color{red} {\div (-4)}\]\[x=-2\]

Answer 3

MAKES SENSE?

Answer 4

thank you, I love how you explains it to me, I have one more.
