How to solve x = 3x + 1? Get the answer and stepwise instruction to solve linear equation in one one variable 𝒙.
We have x + 0 = 3x + 1
First, we move the x terms to the LHS and constant terms to the RHS of the equation, inverting the sign on the terms. This is also called transposing method.
Transposition is a faster method and combines the following two steps, were we to solve the equation by:
i) Subtracting 0 from both sides
ii) Subtracting 3x from both sides
Therefore, x - 3x = 1 - 0
or, -2x = 1
Next, divide both sides by -2, which is the coefficent of xNote: if a = b, then a ÷ c = b ÷ c
-2x/-2 = 1/-2
x = 1/-2 or, x = -0.5
