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
