Question

Н) 8-5=2x+8x О)-11(2-3x)+5x=16 П)13x+(7-5x)=8

Answer 1

Н) 8 - 5 = 2х + 8х               О) -11(2 - 3х) + 5х = 16

3 = 10х                                -22 + 33х + 5х = 16

х = 3 : 10                              38х = 16 + 22

х = 0,3                                 38х = 38

                                           х = 38 : 38

                                           х = 1

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

П) 13х + (7 - 5х) = 8

13х + 7 - 5х = 8

13х - 5х = 8 - 7

8х = 1

х = 1 : 8

х = 1/8 (или 0,125 в десятичных дробях)

Answer 2

It seems like you've provided a system of three equations with three variables (x and two unknowns: Н, О, and П). To solve for these variables, we'll solve each equation one by one.

Equation Н: 8 - 5 = 2x + 8x Simplify the left side: 3 = 10x Divide both sides by 10: x = 3/10 or 0.3

Equation О: -11(2 - 3x) + 5x = 16 Distribute the -11: -22 + 33x + 5x = 16 Combine like terms: 38x - 22 = 16 Add 22 to both sides: 38x = 38 Divide both sides by 38: x = 1

Equation П: 13x + (7 - 5x) = 8 Distribute the negative sign: 13x + 7 - 5x = 8 Combine like terms: 8x + 7 = 8 Subtract 7 from both sides: 8x = 1 Divide both sides by 8: x = 1/8 or 0.125

Now we have values for x from each equation: x = 0.3, x = 1, and x = 0.125. However, it seems that there might be a mistake in the given equations or their transcription since the values of x are not consistent across the equations. Please double-check the equations, and if there is an error, provide the correct equations so that I can help you solve the system accurately.
