Given the numerical equation:
0.2(x + 50) - 6 = 0.4(3x + 20)
Solve for x.
Solution:
In order to solve for x, we distribute 0.2 and 0.4 to their corresponding parenthesis.
0.2(x + 50) - 6 = 0.4(3x + 20)
0.2x + 10 - 6 = 1.2 x + 8
0.2x + 4 = 1.2 x + 8
Transpose 8 and 0.2 x to their opposite sides, hence we must take note that in transposing a number, the sign changes.
4 - 8 = 1.2x- 0.2x
-4 = x
Final answer:
x = -4
