Answer 3

Let's solve the equation step by step:

0.2(x - 9) = 0.3(7 - x) + 0.6

First, let's simplify the equation by distributing the values inside the parentheses:

0.2x - 1.8 = 2.1 - 0.3x + 0.6

Next, let's combine like terms:

0.2x + 0.3x = 2.1 + 0.6 + 1.8

0.5x = 4.5

To isolate x, divide both sides of the equation by 0.5:

x = 4.5 / 0.5

x = 9

Therefore, the solution to the equation 0.2(x - 9) = 0.3(7 - x) + 0.6 is x = 9.
