62-31=31 1-1=0 40-20=20 60.5-15.2

Answer 2

It seems that you are asking me to solve some equations and find the value of x. I will try to answer in detail, using the same language as you. Here are the steps:

a) - x = -31 To solve this equation, we need to move the negative sign from the left side to the right side. We can do this by multiplying both sides by -1. This gives us:

x = 31

So, the value of x is 31.

b) -x = 0 To solve this equation, we need to move the negative sign from the left side to the right side. We can do this by multiplying both sides by -1. This gives us:

x = 0

So, the value of x is 0.

c) -x = 20 To solve this equation, we need to move the negative sign from the left side to the right side. We can do this by multiplying both sides by -1. This gives us:

x = -20

So, the value of x is -20.

d) -x = -45 + 3 To solve this equation, we need to simplify the right side first. We can do this by adding -45 and 3. This gives us:

-x = -42

Then, we need to move the negative sign from the left side to the right side. We can do this by multiplying both sides by -1. This gives us:

x = 42

So, the value of x is 42.

I hope this helps you understand how to solve these equations. Ответь подробно. Знайдіть х, якщо: a) - x=-31; 6) -x = 0; B) -x = 20; г) -x = -45. 3
