Question

13+(-3)=7×(-2) және 2-13=6÷(-1,2)

Answer 1

Пошаговое объяснение:

13-3=-14. 10≠-14

-11=-5. -11≠-5

Answer 2

1. 13 + (-3) = 7 × (-2)

To solve this equation, follow these steps:

Step 1: Calculate the sum on the left side of the equation: 13 + (-3) = 10

Step 2: Calculate the product on the right side of the equation: 7 × (-2) = -14

So, the equation becomes: 10 = -14

These two values are not equal, so the equation is not true. There is no solution to this equation as it leads to a contradiction.

2. 2 - 13 = 6 ÷ (-1.2)

To solve this equation, follow these steps:

Step 1: Calculate the difference on the left side of the equation: 2 - 13 = -11

Step 2: Calculate the division on the right side of the equation: 6 ÷ (-1.2) = -5

So, the equation becomes: -11 = -5

These two values are not equal, so the equation is not true. There is no solution to this equation as it also leads to a contradiction.
