Question

№3: 0,2х+2,7=1,4-1,х №4: 5,4-1,5х=0,3х-3,6 Кто может решите пожалуйста

Answer 1

3) 0,2x + 1x = 1,4 - 2,7
1,2x = -1,3
x= 13/12
4) -1,5x - 0,3x = -3,6 - 5,4
-1,8x = - 9
x = 5

Answer 2

Equation 3: 0.2x + 2.7 = 1.4 - 1x

To solve this equation, we need to isolate the variable x on one side of the equation. Let's start by simplifying both sides of the equation:

0.2x + 2.7 = 1.4 - 1x

Combining like terms:

0.2x + 1x = 1.4 - 2.7

1.2x = -1.3

Now, let's isolate x by dividing both sides of the equation by 1.2:

(1.2x)/1.2 = (-1.3)/1.2

x = -1.3/1.2

Simplifying the right side:

x ≈ -1.083

Therefore, the solution to equation 3 is approximately x = -1.083.

Equation 4: 5.4 - 1.5x = 0.3x - 3.6

To solve this equation, we will follow a similar process as before. Let's simplify both sides of the equation:

5.4 - 1.5x = 0.3x - 3.6

Combining like terms:

1.5x + 0.3x = 5.4 + 3.6

1.8x = 9

Now, let's isolate x by dividing both sides of the equation by 1.8:

(1.8x)/1.8 = 9/1.8

x = 9/1.8

Simplifying the right side:

x = 5

Therefore, the solution to equation 4 is x = 5.

Please note that these solutions are approximate and may be rounded to a certain number of decimal places.
