Question 303160
Well if your problem is coppied correctly, all you have to do is add 3 to both sides.
Given: {{{(X - 3) = 27}}}
Since the (X - 3) is by itself and is not multiplied or divided by anything, you can drop the parenthesis.
{{{X - 3 = 27}}} Now add 3 to both sides
{{{X = 27 + 3}}}
{{{highlight(X = 30)}}}
