Question

5(4-x)+3=2(x+1,5) Решение

Answer 1

Объяснение:

20-5х+3=2х+3

-5х-2х=3-3+20

-7х=20

х=20÷(-7)

х=2целых 6/7

Answer 2

20-5х+3=2х+3
-5х-2х=3-20-3
-7х=-20
х=-20:(-7)
х=20/7
х=2 6/7

Answer 3

To solve the equation 5(4 - x) + 3 = 2(x + 1.5), we can follow these steps:

1. Distribute the multiplication on both sides of the equation: 20 - 5x + 3 = 2x + 3

2. Combine like terms: -5x + 23 = 2x + 3

3. Move the variables to one side and the constants to the other side of the equation: -5x - 2x = 3 - 23

   Simplifying: -7x = -20

4. Divide both sides by -7 to solve for x: x = -20 / -7

   Simplifying: x = 20/7

Therefore, the solution to the equation 5(4 - x) + 3 = 2(x + 1.5) is x = 20/7.
