Question

8х+3(7-2х)=4х+323-4+(3х+8)=1-17х​

Answer 1

Ответ:

1) 8x + 3(7-2x) = 4x+3

8x + 21 - 6x = 4x + 3

2x + 21 = 4x + 3

2x - 4x = 3 - 21

-2x = -18

x=9

2) 23 - 4 + (3х + 8) = 1 - 17

23 - 4 + 3х+8 = -16

27 + 3х = -16

3х = -16 - 27

3х = -43

х=-43/3=-14 1/3

Answer 2

To solve the equation 8x + 3(7 - 2x) = 4x + 323 - 4 + (3x + 8) = 1 - 17x, let's break it down step by step.

Step 1: Start by simplifying each part of the equation separately.

8x + 3(7 - 2x) = 4x + 323 - 4 + (3x + 8) = 1 - 17x

First, simplify the expressions within parentheses and combine like terms.

8x + 21 - 6x = 4x + 319 + 3x + 8 = 1 - 17x

Now, simplify each part:

(8x - 6x) + 21 = (4x + 3x) + (319 + 8) = 1 - 17x

2x + 21 = 7x + 327 = 1 - 17x

Step 2: Now, let's isolate the variable x on one side of the equation. We'll start with the left side:

2x + 21 = 7x + 327

Subtract 7x from both sides to move all x terms to the left side:

2x - 7x + 21 = 327

-5x + 21 = 327

Step 3: Next, subtract 21 from both sides to isolate the -5x term:

-5x + 21 - 21 = 327 - 21

-5x = 306

Step 4: Now, divide both sides by -5 to solve for x:

(-5x) / (-5) = 306 / (-5)

x = -306 / 5

Now, we can simplify this fraction:

x = -61.2

So, the solution to the equation is:

x = -61.2
