Question

4,5х+2х-2/3×(8х-10)=4​

Answer 1

Ответ:

4,5х+2х-2/3×(8х-10)=4​

4,5х+2х-16х/3+20/3=4

(6,5х*3)/3-16х/3+20/3=4*3

19,5х-16х+20=12

3,5х=12-20

х=-8/3,5

х= -2 2/7

Answer 2

It seems like you have an equation that you'd like to solve for the variable x. Let's work through it step by step.

The equation you've provided is:

4.5x + 2x - 2/3 * (8x - 10) = 4

First, let's simplify the equation by distributing the -2/3 into the expression (8x - 10):

4.5x + 2x - (2/3) * 8x + (2/3) * 10 = 4

Now, let's simplify each term:

(4.5x + 2x) - (2/3 * 8x) + (2/3 * 10) = 4

Combine like terms:

6.5x - (16/3)x + (20/3) = 4

Now, let's get rid of the fractions by multiplying both sides of the equation by 3 to clear the denominators:

3 * (6.5x) - 3 * (16/3)x + 3 * (20/3) = 4 * 3

This simplifies to:

19.5x - 16x + 20 = 12

Now, combine like terms:

3.5x + 20 = 12

Next, subtract 20 from both sides to isolate the variable x:

3.5x = 12 - 20 3.5x = -8

Finally, divide both sides by 3.5 to solve for x:

x = -8 / 3.5

Now, you can simplify this fraction further if needed:

x ≈ -2.2857 (rounded to four decimal places)

So, the solution to the equation is approximately x ≈ -2.2857.
