Answer 2

To solve this equation, let's simplify and solve for 'x'.

0.35(0.35x - 1) - 0.45(0.45x - 2) = 0.55(0.55x - 3) - 0.65(0.65x - 4)

First, distribute the constants and simplify the equation:

0.1225x - 0.35 - 0.2025x + 0.9 = 0.3025x - 1.65 - 0.4225x + 2.6

Now, combine like terms on both sides of the equation:

(0.1225x - 0.2025x - 0.3025x + 0.4225x) - (-0.35 + 0.9 - 1.65 + 2.6) = 0

Combine the x terms and the constants:

0.04x + 0.55 = 0

Now, subtract 0.55 from both sides to isolate 'x':

0.04x = -0.55

Finally, divide both sides by 0.04 to solve for 'x':

x = -0.55 / 0.04 x = -13.75

So, the solution to the equation is x = -13.75.
