Answer 1

We want to solve an equation, so we only need to use simple algebra.

The solution is: x = 3

The original equation is:

0.2*(15*x - 20) = 0.5*(16 - 2*x)

To solve this, we need to move all the terms with "x" to the same side, so first we need to expand.

0.2*15*x - 0.2*20 = 0.5*16 - 0.5*2*x

We can move all the terms with x to the left side, and the others to the right side:

0.2*15*x + 0.5*2*x = 0.5*16 + 0.2*20

3*x + 1*x = 12

4*x = 12

Now we can divide both sides by 4:

x = 12/4 = 3

x = 3
