Explanation:
12-4x=11
to solve this Linear equation, always make x to stand by itself,
to do so, let's. subtract 12 from both sides of equations that is we collect like terms
12-12-4x= 11-12
positive 12 and negative 12 cancel
-4x = -1
we need to solve for x
let's divide both sides of the equation by -4
-4x/-4=-1/-4
Note that negative divided by negative is positive
x= 1/4
