Question

9 x - 0,7 = 2 - 4 ( 1 + x )

Answer 1

9x-0,7=-2-4x
9x+4x=-2+0,7
13x=-1.3
X=-1.3/13
X=-0,1

Answer 2

9х-0.7=2-4+4х
9х-4х=2,4+0,7
5х=3.1
х=0,62

Answer 3

To solve the equation 9x - 0.7 = 2 - 4(1 + x), follow these steps:

1. Distribute the -4 on the right side of the equation: 9x - 0.7 = 2 - 4 - 4x

2. Combine like terms on the right side: 9x - 0.7 = -2 - 4x

3. Move the -4x from the right side to the left side by adding 4x to both sides of the equation: 9x + 4x - 0.7 = -2

4. Combine like terms on the left side: 13x - 0.7 = -2

5. To isolate the variable x, add 0.7 to both sides of the equation: 13x = -2 + 0.7

6. Simplify the right side: 13x = -1.3

7. Finally, divide both sides by 13 to solve for x: x = -1.3 / 13

Now, calculate the value of x: x = -0.1

So, the solution to the equation is x = -0.1.
