Answer 1

Ответ:

Пошаговое объяснение:

1.) 5-3(2x-1)=4x-22

5-6х+3=4х-22

-6х-4х=-22-3-5

-10х=14

х=14:(-10)

х=-1.4

2.) 1,2c-7=6c-16,6

1.2с-6с=7-16.6

-4.8с=-9.6

с=-9.6:(-4.8)

с=2

Answer 3

1.)

Starting with the left-hand side of the equation:

5 - 3(2x - 1)

= 5 - 6x + 3

= 8 - 6x

Now we can set this equal to the right-hand side of the equation and solve for x:

8 - 6x = 4x - 22

Add 6x to both sides:

8 = 10x - 22

Add 22 to both sides:

30 = 10x

Divide both sides by 10:

x = 3

Therefore, the solution to the equation is x = 3.

2.)

Starting with the left-hand side of the equation:

1.2c - 7 = 6c - 16.6

Adding 16.6 and 7 to both sides:

1.2c + 9.6 = 6c

Subtracting 1.2c from both sides:

9.6 = 4.8c

Dividing both sides by 4.8:

c = 2

Therefore, the solution to the equation is c = 2.
