Question

45,7 x+0,3 x-2,4=89,6 80.1y-10.1+4.7=81.7

Answer 1

1)45,7 x+0,3 x-2,4=89,6
   46х-2.4=89,6
   46х=89,6+2,4
   46х=92
   х=92:46
   х=2
Ответ:2

2)80.1y-10.1+4.7=81.7
   80,1у-5.4=81,7
   80,1у=81,7+5,4
   80,1у=87,1
   у=87,1:80,1
   у=871/801(дробью)=1(целая)71/801(дробью)
вот!,я не очень уверена,особенно во втором.прости если что!

Answer 2

To solve the equation 45.7 + x + 0.3x - 2.4 = 89.6 + 80.1y - 10.1 + 4.7 = 81.7, we'll need to simplify and solve for the variables x and y.

First, let's simplify the equation by combining like terms:

45.7 + 1.3x - 2.4 = 89.6 + 80.1y - 5.4

Now, combine the constants and the x terms on the left side:

44.6 + 1.3x = 84.2 + 80.1y

Next, we can isolate the x term by subtracting 44.6 from both sides:

1.3x = 84.2 + 80.1y - 44.6

1.3x = 39.6 + 80.1y

Now, let's solve for x by dividing both sides by 1.3:

x = (39.6 + 80.1y) / 1.3

This gives us the value of x in terms of y.

To solve for y, we can start by simplifying the equation to isolate the terms with y:

80.1y = 1.3x - 39.6

Now, divide both sides by 80.1 to solve for y:

y = (1.3x - 39.6) / 80.1

So, the solution to the given equation is:

x = (39.6 + 80.1y) / 1.3 y = (1.3x - 39.6) / 80.1

These equations express x and y in terms of each other, providing a relationship between the two variables.
