Answer 2

1. А) 6у - 6 = 7у - 2: To solve this equation, we can start by simplifying both sides of the equation. Let's combine like terms:

6у - 7у = -2 + 6

Simplifying further:

-y = 4

To isolate y, we can multiply both sides of the equation by -1:

y = -4

Therefore, the solution to the equation 6у - 6 = 7у - 2 is y = -4.

Б) 3.6м + 4 = -4м + 17: To solve this equation, we can start by simplifying both sides of the equation. Let's combine like terms:

3.6м + 4м = 17 - 4

Simplifying further:

7.6м = 13

To isolate м, we can divide both sides of the equation by 7.6:

м = 13 / 7.6

Calculating the value:

м ≈ 1.71

Therefore, the solution to the equation 3.6м + 4 = -4м + 17 is м ≈ 1.71.

В) 2b + 6 = -3b + 16: To solve this equation, we can start by simplifying both sides of the equation. Let's combine like terms:

2b + 3b = 16 - 6

Simplifying further:

5b = 10

To isolate b, we can divide both sides of the equation by 5:

b = 10 / 5

Calculating the value:

b = 2

Therefore, the solution to the equation 2b + 6 = -3b + 16 is b = 2.

г) 3(z - 2) = z + 8: To solve this equation, we can start by distributing the 3 on the left side of the equation:

3z - 6 = z + 8

Next, let's isolate z by moving all terms with z to one side of the equation:

3z - z = 8 + 6

Simplifying further:

2z = 14

To isolate z, we can divide both sides of the equation by 2:

z = 14 / 2

Calculating the value:

z = 7

Therefore, the solution to the equation 3(z - 2) = z + 8 is z = 7.

Д) x - 19 = 1 + 3x: To solve this equation, we can start by simplifying both sides of the equation. Let's combine like terms:

x - 3x = 1 + 19
