Given the numerical equation:

0.3x-(0.8-0.2x)=0.2-0.5x​

Solve for x.

Solution:

In order to solve for x, we must simply combine similar terms in the numerical equation.

0.3x-(0.8-0.2x)=0.2-0.5x​

0.3x - 0.8 + 0.2x = 0.2 - 0.5x

0.5x - 0.8 = 0.2 - 0.5x

Transpose -0.5x and -0.8 on the opposite sides of the equation, hence we must take note that in transposing a number, the sign changes.

0.5x + 0.5x = 0.2 + 0.8

x = 1

Final answer:

x = 1
