Answer 1

Пошаговое объяснение:

-6+8-10-х=-3

-8-х+3=0

-5-х=0

-Х=-5

Х=5

11-5z=12-6z

11-5z-12+6z=0

Z-1=0

Z=1

-9a+8=-10a-2

-9a+8+10a+2=0

A+10=0

A=-10

Answer 2

Ответ:

-x=-3+6-8+10

-x=-5

×=5

-5z+6z=12-11

z=1

-9a+10a=-2-8

a=-10

Answer 3

Let's solve each equation step-by-step:

1. -6 + 8 - 10x = -3

First, combine the constants on the left side of the equation:

-6 + 8 = 2

The equation becomes:

2 - 10x = -3

Next, isolate the variable x by moving the constant term to the other side:

-10x = -3 - 2 -10x = -5

Now, divide both sides by -10 to solve for x:

x = -5 / -10 x = 1/2

So, the solution for the first equation is x = 1/2.

2. 11 - 5z = 12 - 6z

Start by moving the variable term to one side and the constant term to the other side:

-5z + 6z = 12 - 11 -z = 1

Now, isolate the variable z by multiplying both sides by -1:

z = -1

The solution for the second equation is z = -1.

3. -9a + 8 = -10a - 2

Begin by moving the variable term to one side and the constant term to the other side:

-9a + 10a = -2 - 8 a = -10

The solution for the third equation is a = -10.

To summarize:

1. x = 1/2
2. z = -1
3. a = -10
