If the question is set with a fraction, you should not change it to a decimal. Add 1/2 to each side of the equation to get:
x = 4 1/2.

x-1/2=4
+1/2 +1/2
x=4 1/2

x - 1/2 = 4
Multiply through by 2 to get rid of the fraction.
2x - 1 = 8
Add +1 to each side to get rid of the -1
2x = 9
Divide both sides by 9 to find x
x = 9/2 or 4 1/2 or 4.5

First one: ingredient out x+a million. in spite of if, do no longer forget approximately that a root of x +a million -- i.e., x = -a million -- is likewise a answer. formally, you could write the equation as (x+a million)*(3x + 3 - 4) = 0, and the ideas happen whilst the two of those 2 words = 0. 2nd one: enable u = ax +b and v = bx + a. u^2 - v^2 = 0. (u-v) * (u+v) = 0. u-v = 0 or u+v = 0. replace lower back in for u and v any time you like, and clean up for x. the huge ingredient right this is that a fabricated from words equals 0 if and on condition that ANY of the words equals 0. So be careful in case you ingredient something out that could equivalent 0.
