Question

4*5(2х-1.3)=9*5х+2.1

Answer 1

Ответ: Х = -5,62

Пошаговое объяснение:

20 (2х - 1,3) = 45х + 2,1

4х - 26 = 45х + 2,1

40х - 45х = 2,1 + 26

-5х = 28,1

Х = -5,62

Answer 2

20(2х-1,3)=45х+2,1
4х-26=45х+2,1
40х-45х=2,1+26
-5х=28,1
Х=-5,62

Answer 3

To solve the equation 45(2x - 1.3) = 95x + 2.1, we'll follow the order of operations and simplify the expression step by step.

1. Distribute the multiplication: 20x - 13 = 45x + 2.1

2. Move the variables (terms with x) to one side of the equation and the constants to the other side: 20x - 45x = 2.1 + 13

-25x = 15.1

3. Divide both sides by -25 to solve for x: x = 15.1 / -25

Simplifying the division gives us: x = -0.604

Therefore, the solution to the equation 45(2x - 1.3) = 95x + 2.1 is x = -0.604.
