Question

5x+(3x+2)=(4x-8)+x+20

Answer 1

Ответ:

5х+3х+2=4х-8+х+20

8х+2=5х+12

8х-5х=12-2

3х=10

х=10:3

х=3,3

Answer 2

To solve the equation 5x + (3x + 2) = (4x - 8) + x + 20, you'll want to simplify and isolate the variable x. Here are the steps to solve it:

1. Begin by simplifying both sides of the equation by combining like terms.

On the left side: 5x + 3x + 2 becomes 8x + 2.

On the right side: (4x - 8) + x + 20 becomes 5x + 12.

So, the equation now looks like this: 8x + 2 = 5x + 12.

2. Next, subtract 5x from both sides of the equation to isolate the variable x on one side.

8x + 2 - 5x = 5x + 12 - 5x.

This simplifies to: 3x + 2 = 12.

3. Now, subtract 2 from both sides of the equation to further isolate 3x.

3x + 2 - 2 = 12 - 2.

This simplifies to: 3x = 10.

4. Finally, divide both sides by 3 to solve for x:

(3x) / 3 = 10 / 3.

x = 10 / 3.

So, the solution to the equation is x = 10/3 or approximately x = 3.33 (rounded to two decimal places).
