Ответ:

1)42

2)3

3)4

Пошаговое объяснение:

1)х-24=18

х=18+24

2)8х-18-5=1

8х=24

3)14х-21-23=13

14х=56

Answer 3

Let's solve each of these equations step by step:

1. • (4 × 6) = 18

First, calculate the product inside the parentheses:

• (4 × 6) = -24

Now, you have:

• (-24) = 18

To solve for the variable (in this case, there's no variable), simplify the equation:

-24 = 18

This equation is not true because -24 does not equal 18. There seems to be an error in the equation.

2. 2(4 × -9) - 5 = 1

First, calculate the product inside the parentheses:

2(4 × -9) = 2(-36) = -72

Now, you have:

-72 - 5 = 1

Combine the terms on the left side:

-72 - 5 = -77

Now, the equation is:

-77 = 1

This equation is also not true because -77 does not equal 1.

3. 7(2 × -3) - 23 = 12

First, calculate the product inside the parentheses:

7(2 × -3) = 7(-6) = -42

Now, you have:

-42 - 23 = 12

Combine the terms on the left side:

-42 - 23 = -65

Now, the equation is:

-65 = 12

This equation is not true either because -65 does not equal 12.

It seems there may be errors in the original equations you provided, as none of them have valid solutions based on the given equations. Please double-check the equations or provide more context if needed.
