Hey there!

Distribute
\bf{3} within the parentheses!


\bold{3(4x - 2)=27}\\ \bold{3(4x) +3(-2)}\\ \bf{3(4x) =12x}\\ \bf{3(-2)=-6

NEW EQUATION


\bold{12x -6 = 27}

Add by
\bold{6} on BOTH SIDES


\bf{12x-6+6=27+6}

CANCEL out:
\bf{-6+6 because that gives you
\bf{0}

KEEP:
\bf{27 +6} because it helps us solve for your
\bf{x}


\bf{27+6=33}

NEW EQUATION


\bf{12x=33}

DIVIDE by
\bf{12} on BOTH SIDES


\bf{(12x)/(12) =(33)/(12)}

CANCEL out:
\bf{(12x)/(12)} because that gives you
\bf{1}

KEEP:
\bf{(33)/(12)} because it gives you your
\bf{x}


\bf{(33)/(12)=(11)/(4)}


\boxed{\bold{Answer: x = (11)/(4)}}\checkmark

Good luck on your assignment and enjoy your day!
