Question

3/5(3-2х)=2/5(9-х)-0,3(х-9)

Answer 1

Ответ:

-9

Пошаговое объяснение:

1,8-1,2х=3,6-0,4х-0,3х+2,7

1,8-1,2х=6,3-0,7х

0,7х-1,2х=6,3-1,8

-0,5х=4,5

х=4,5/-0,5=4,5×(-2)

х=-9

Answer 2

To solve the equation, we need to find the value of the variable "х" that satisfies the equation. Let's start by simplifying and solving step-by-step:

1. Distribute the coefficients on the right side of the equation: 3/5(3 - 2х) = 2/5(9 - х) - 0.3(х - 9)

   Multiply each term inside the parentheses by its respective coefficient: (3/5) * 3 - (3/5) * 2х = (2/5) * 9 - (2/5) * х - 0.3 * х + 0.3 * 9

2. Simplify further: (9/5) - (6/5)х = (18/5) - (2/5)х - 0.3х + 2.7

3. Combine "х" terms on the right side: (9/5) - (6/5)х = (18/5) - (2/5 + 0.3)х + 2.7

4. Combine constant terms on the right side: (9/5) - (6/5)х = (18/5) - (5/5)х + 2.7

5. Now, isolate "х" on one side of the equation. To do this, move all "х" terms to the left side and constant terms to the right side: (6/5)х - (5/5)х = (18/5) - (9/5) + 2.7

6. Combine "х" terms on the left side: (6/5 - 5/5)х = (18/5) - (9/5) + 2.7

7. Simplify: (1/5)х = (9/5) + 2.7

8. Combine constant terms on the right side: (1/5)х = (9/5) + 2.7

9. Now, isolate "х" by multiplying both sides by 5 to get rid of the fraction: х = 5 * ((9/5) + 2.7)

10. Calculate the value of "х": х = 5 * (1.8 + 2.7) х = 5 * 4.5 х = 22.5

So, the solution to the equation is х = 22.5.
