Question

4(3x - 5)-2- 4x +9) = - 2x​

Answer 1

Ответ:

4(3x - 5)-2- 4x +9) = - 2x

Скобочка одна не стоит(

Но я попробую предположить где она должна быть.

4(3x - 5)-2- (4x +9) = - 2x

тогда будет:

12х-20-2-4х-9+2х=0

10х-31=0

10х=31

х=3,1

Answer 2

Ответ:

1) 4((3x - 5)-2- 4x +9) = - 2x

(3x - 5)-2- 4x +9 = - 0,5x

3x - 5-2- 4x +9 = - 0,5x

-x+2 = -0.5x

2= 0.5x

x=4

2) 4(3x - 5)-2- 4x +9 = - 2x

12x-20-2-4x+9=-2x

12x-4x+2x=20+2-9

10x=13

x=1.3

Answer 3

Let's solve the equation step by step:

1. Start by distributing the numbers outside the parentheses to the terms inside the parentheses: 4(3x - 5) - 2 - (4x + 9) = -2x

   This gives you: 12x - 20 - 2 - 4x - 9 = -2x

2. Now, combine like terms on both sides of the equation. Start by adding or subtracting the constants on each side:

   (12x - 4x) - (20 + 2 + 9) = -2x

   This simplifies to: 8x - 31 = -2x

3. To solve for x, you can isolate the variable on one side of the equation. To do this, add 2x to both sides of the equation to move all the x terms to one side:

   8x + 2x - 31 = 0

   This simplifies to: 10x - 31 = 0

4. Finally, add 31 to both sides to isolate 10x:

   10x - 31 + 31 = 0 + 31

   This simplifies to: 10x = 31

5. To find the value of x, divide both sides by 10:

   (10x) / 10 = 31 / 10

   This simplifies to: x = 31/10

So, the solution to the equation is:

x = 31/10 or x = 3.1
