Question

0,2(3x-5)-0, 3(x-1)=

Answer 1

Ответ:

0,2*(3x-5) - 0,3*(x-1) = 0,6x - 1 - 0,3x +0,3 = 0,3x-0,7

Answer 2

To solve the equation 0.2(3x - 5) - 0.3(x - 1) = 0, we'll simplify and solve for x.

Let's start by distributing the multiplication:

0.2 * 3x - 0.2 * 5 - 0.3 * x + 0.3 * 1 = 0

0.6x - 1 - 0.3x + 0.3 = 0

Next, combine like terms:

(0.6x - 0.3x) - 1 + 0.3 = 0

0.3x - 1 + 0.3 = 0

0.3x - 0.7 = 0

Now, we'll isolate the variable by adding 0.7 to both sides of the equation:

0.3x = 0.7

To solve for x, divide both sides of the equation by 0.3:

x = 0.7 / 0.3

Simplifying the division:

x ≈ 2.3333

Therefore, the solution to the equation 0.2(3x - 5) - 0.3(x - 1) = 0 is approximately x = 2.3333.
