Answer

The solution of this equation is x = 1000.

Work Step by Step

0.08x = 580 - 0.1(6000 - x) Use the distributive property to obtain: 0.08x = 580 - 600 + 0.1x In order to solve for x, we first need to get all of the terms with an x in them on the same side of the equation. Thus, we obtain: 0.08x - 0.1x = 580 - 600 -0.02x = - 20 Divide both sides by -0.02 x = 1000 The solution of this equation is x = 1000.
