Question

36:4+х=36. (25+20):х=9

Answer 1

36:4+х=36
9+х=36
х=36-9
х=27
Ответ: х=27.
-----------------
(25+20):х=9
45:х=9
х=45:9
х=5
Ответ: х=5.

Answer 2

36÷4+х=36
9+х=36
х=36-9
х=27

(25+20) ÷х=9
45÷х=9
х=45÷9
х=5

Answer 3

To solve these equations, we'll find the value of "х" in each case.

1. 36:4 + х = 36

Step 1: Simplify the left-hand side of the equation: 36 ÷ 4 + х = 9 + х

Step 2: Move "9" to the other side of the equation by subtracting it from both sides: 9 + х - 9 = 36 - 9 х = 27

So, the value of "х" in the first equation is 27.

2. (25 + 20) : х = 9

Step 1: Simplify the left-hand side of the equation: 45 ÷ х = 9

Step 2: Move "9" to the other side of the equation by multiplying both sides by "х": 9 * х = 45

Step 3: Solve for "х" by dividing both sides by 9: х = 45 ÷ 9 х = 5

So, the value of "х" in the second equation is 5.
