Answer

x = 0.025

Work Step by Step

2.3 +500x =600x -0.2 2.3 +500x -2.3 =600x -0.2-2.3 500x = 600x -2.5 500x -600x = 600x -2.5 -600x -100x=-2.5 $\frac{-100x}{-100}$=$\frac{-2.5}{-100}$ x=0.025 check Replace x with 0.025 2.3 +500x =600x -0.2 2.3 +500$\times$0.025 =600$\times$0.025 -0.2 2.3 +12.5=15 -0.2 14.8 = 14.8
