Answer 2

Let's break down the two equations one by one:

Equation 1: Х×0,01=0,81+0,009

To solve for X, we need to isolate it on one side of the equation.

We can start by combining the terms on the right side of the equation:

0.81 + 0.009 = 0.819

Now the equation becomes:

X × 0.01 = 0.819

To isolate X, we need to divide both sides of the equation by 0.01:

X = 0.819 / 0.01 = 81.9

So the solution for the first equation is X = 81.9.

Equation 2: X × 0.001 = 2.149 - 1.234

We can simplify the right side of the equation by subtracting 1.234 from 2.149:

2.149 - 1.234 = 0.915

Now the equation becomes:

X × 0.001 = 0.915

To isolate X, we need to divide both sides of the equation by 0.001:

X = 0.915 / 0.001 = 915

So the solution for the second equation is X = 915.

Therefore, the solutions for the given set of equations are X = 81.9 and X = 915.
