Question

1) x-6/x+9=7/44(x-6)=7(x-9)x=2) x-2,4/6=x+0,6/11x=​

Answer 1

Ответ:

(x-6) * 4 = (x+9) * 7

4x-24=7x-63

4x-7x=63+24

-3x=87

x=87 / (-3)

x=-29

(x-2,4) / 6 = (x+0,6) / 11

11 * ((x-2,4) / 6) = 6 * ((x+0,6) / 11)

(11x-26.4) / 66 = (6x+3.6) / 66

11x-26.4 = 6x+3.6

11x-6x=3.6+26.4

5x=30

x=30/5

x=6

Answer 2

Ответ:

x=6

Объяснение:

(x-6) * 4 = (x+9) * 7

4x-24=7x-63

4x-7x=63+24

-3x=87

x=87 / (-3)

x=-29

(x-2,4) / 6 = (x+0,6) / 11

11 * ((x-2,4) / 6) = 6 * ((x+0,6) / 11)

(11x-26.4) / 66 = (6x+3.6) / 66

11x-26.4 = 6x+3.6

11x-6x=3.6+26.4

5x=30

x=30/5

x=6

Answer 3

To solve the first equation, let's simplify it step by step:

1. Multiply both sides of the equation by (x + 9) to eliminate the denominators: (x - 6)/(x + 9) = 7/44 44(x - 6) = 7(x + 9)

2. Expand both sides of the equation: 44x - 264 = 7x + 63

3. Combine like terms: 44x - 7x = 63 + 264 37x = 327

4. Divide both sides by 37 to solve for x: x = 327/37 x ≈ 8.8378

Therefore, the solution to the first equation is approximately x ≈ 8.8378.

Now let's solve the second equation:

1. Multiply both sides of the equation by 6 to eliminate the denominators: 6(x - 2) + 4 = x + 0.6(11x)

2. Expand and simplify: 6x - 12 + 4 = x + 6.6x

3. Combine like terms: 6x - 8 = 7.6x

4. Subtract 6x from both sides: -8 = 1.6x

5. Divide both sides by 1.6 to solve for x: x = -8/1.6 x = -5

Therefore, the solution to the second equation is x = -5.
