Question

Решите уравнения а) ((x+5)-2)+7=37 б) ((x-27)-36)+30=143помогите пожалуйста

Answer 1

А) ((x+5)-2)+7=37
x=37-5+2-7
x=27
Ответ. x=27
б) ((x-27)-36)+30=143
x=143+27+36-30
x=176
Ответ. x=176

Answer 2

( X + 5 ) - 2 = 37 - 7 
( X + 5 ) - 2 = 30 
X + 5 = 30 + 2
X + 5 = 32 
X = 32 - 5 
X = 27 
------------------------
( X - 27 ) - 36 = 143 - 30 
( X - 27 ) - 36 = 113 
X - 27 = 113 + 36 
X - 27 = 149 
X = 149 + 27 
X = 176

Answer 3

Solving the Equations

Let's solve the given equations step by step:

a) ((x + 5) - 2) + 7 = 37

To solve this equation, we will simplify the expression inside the parentheses first:

(x + 5) - 2 = x + 3

Now, we substitute this simplified expression back into the original equation:

(x + 3) + 7 = 37

Next, we combine like terms:

x + 3 + 7 = 37

Simplifying further:

x + 10 = 37

To isolate the variable x, we subtract 10 from both sides of the equation:

x + 10 - 10 = 37 - 10

This gives us:

x = 27

Therefore, the solution to the equation a) is x = 27.

b) ((x - 27) - 36) + 30 = 143

Again, let's simplify the expression inside the parentheses first:

(x - 27) - 36 = x - 63

Now, we substitute this simplified expression back into the original equation:

(x - 63) + 30 = 143

Next, we combine like terms:

x - 63 + 30 = 143

Simplifying further:

x - 33 = 143

To isolate the variable x, we add 33 to both sides of the equation:

x - 33 + 33 = 143 + 33

This gives us:

x = 176

Therefore, the solution to the equation b) is x = 176.

Summary

The solutions to the given equations are: a) x = 27 b) x = 176
