Given the numerical equation:

3/10x - 1/5 = 1

Solve for x.

Solution:

In order to solve for x, we simply need to multiply 10x first on both sides of the equation, in order to cancel out 3/10x

3/10x - 1/5 = 1

(10x) (3/10x - 1/5) = (10x) (1)

3 - 10x/5 = 10x

3 - 2x = 10x

Transpose -2x to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

3 = 10x + 2x

12x = 3

Divide both sides by 12 in order to cancel out 12x, leaving behind x.

12x/12 = 3/12

x = ¼

Final answer:

x = ¼
