Question

Решить уравнение( 35.8-x)/2.1=1.3

Answer 1

(35,8-x)/2,1=1,3

35,8-х=1,3/2,1

35,8-х=2,73

х=35,8-2,73

х=33,07

Answer 2

(35,8-x)/2,1=1,3

35,8-x=2,1*1,3

35,8-x=2,73

x=35,8-2,73

x=33,07

Answer 3

To solve the equation $\frac{{35.8-x}}{{2.1}} = 1.3$, you need to isolate the variable $x$ on one side of the equation. Follow these steps:

Step 1: Remove the fraction by multiplying both sides of the equation by 2.1 to cancel out the denominator: $2.1 \times \left(\frac{{35.8-x}}{{2.1}}\right) = 2.1 \times 1.3$

Step 2: Simplify both sides of the equation: $35.8 - x = 2.73$

Step 3: Now, isolate $x$ by moving the constant term (35.8) to the other side of the equation. Do this by subtracting 35.8 from both sides: $35.8 - x - 35.8 = 2.73 - 35.8$

Step 4: Simplify both sides of the equation: $-x = -33.07$

Step 5: Finally, solve for $x$ by multiplying both sides by -1 to get $x$ by itself: $x = 33.07$

So, the solution to the equation is $x = 33.07$.
