1). 21*(x-8):2=10 2). 1/2*(x-5)-10=22 Решите пожалуйста.

Answer 1

Одна друга (х-5)=22+10
одна друга (х-5)=32
х-5=32:одну другу
х-5=64
х=64+5
х=69

Answer 2

Equation 1: 21*(x-8)/2 = 10

To solve the equation 21*(x-8)/2 = 10, we can follow these steps:

Step 1: Simplify the equation by multiplying both sides by 2 to eliminate the fraction: 21*(x-8) = 20

Step 2: Distribute the 21 to the terms inside the parentheses: 21x - 168 = 20

Step 3: Add 168 to both sides to isolate the variable term: 21x = 188

Step 4: Divide both sides by 21 to solve for x: x = 188/21

Therefore, the solution to the equation 21*(x-8)/2 = 10 is x = 188/21.

Equation 2: 1/2*(x-5) - 10 = 22

To solve the equation 1/2*(x-5) - 10 = 22, we can follow these steps:

Step 1: Simplify the equation by multiplying both sides by 2 to eliminate the fraction: (x-5) - 20 = 44

Step 2: Combine like terms on the left side: x - 5 - 20 = 44

Step 3: Simplify the left side: x - 25 = 44

Step 4: Add 25 to both sides to isolate the variable term: x = 69

Therefore, the solution to the equation 1/2*(x-5) - 10 = 22 is x = 69.
