Question

1. 3x-10=0 2. 5x+11=3x 3. 7x-6=7x 4. 6+x=-3x

Answer 1

1. 3x-10=0

3x=10

x=10/3

2. 5x+11=3x

5x-3x=-11

2x=-11

x=-11/2

3. 7x-6=7x

0x=6

x- не имеет корней

4. 6+x=-3x

4x=-6

x=-3/2

Answer 3

Let's solve each equation step by step:

1. 3x - 10 = 0

To solve this equation, we want to isolate the variable x.

Adding 10 to both sides of the equation, we have:

3x = 10

Now, we can divide both sides of the equation by 3 to solve for x:

x = 10/3

Therefore, the solution to the equation is x = 10/3.

2. 5x + 11 = 3x

Similarly, we want to isolate the variable x.

Subtracting 3x from both sides of the equation, we have:

2x + 11 = 0

Subtracting 11 from both sides of the equation:

2x = -11

Dividing both sides of the equation by 2, we get:

x = -11/2

Therefore, the solution to the equation is x = -11/2.

3. 7x - 6 = 7x

In this equation, notice that we have 7x on both sides of the equation. Subtracting 7x from both sides, we get:

-6 = 0

However, this equation has no solution because -6 is not equal to 0. Therefore, there is no value of x that satisfies this equation.

4. 6 + x = -3x

To solve this equation, we want to isolate the variable x.

Adding 3x to both sides of the equation, we have:

4x + 6 = 0

Subtracting 6 from both sides of the equation:

4x = -6

Dividing both sides of the equation by 4, we get:

x = -6/4

Simplifying further, we have:

x = -3/2

Therefore, the solution to the equation is x = -3/2.
