Question

-0.4(1.5x-2)=1-0.5(2x+1)

Answer 1

-0,6x+0,8=1-x-0,5
-0,6x+x=1-0,5-0,8
0,4x=-0,3
x=-0,75
Ответ:-0,75

Answer 2

To solve the equation, let's simplify and solve step by step:

-0.4(1.5x - 2) = 1 - 0.5(2x + 1)

Start by distributing the -0.4 and -0.5 terms:

-0.6x + 0.8 = 1 - x - 0.5

Next, combine like terms:

-0.6x + 0.8 = 0.5 - x

To isolate the x term, we'll move all terms containing x to one side of the equation:

-0.6x + x = 0.5 - 0.8

Combine the x terms and the constant terms:

0.4x = -0.3

Finally, divide both sides of the equation by 0.4 to solve for x:

x = -0.3 / 0.4

x ≈ -0.75

Therefore, the solution to the equation is x ≈ -0.75.
