Question

Х=(х+270)*0,10​

Answer 1

0,1х-х+27=0

-0,9х=-27

х=30

Answer 2

$x = (x + 270) \times 0.1 \\ (x + 270) \times 0.1 - x = 0 \\ 0.1x + 27 - x = 0 \\ - 0.9x = - 27 \\ x = 30$

Answer 3

It seems like you have provided an equation, but it's not clear what you want to do with it. The equation you provided is:

Х = (х + 270) * 0.10

It appears to be a simple mathematical expression, where Х (capital "X") is equal to the result of multiplying the value of х (small "x") added to 270, by 0.10 (which is equivalent to multiplying by 10% or dividing by 10).

If you want to calculate the value of Х for a specific value of х, you simply need to substitute that value into the equation and solve for Х. For example, if х is 100:

Х = (100 + 270) * 0.10 Х = 370 * 0.10 Х = 37

So, when х is 100, Х would be 37.
