Question

((x-14) 7+18):9 = 9;​

Answer 1

Ответ:

Let's solve the equation step by step:

((x-14) 7+18):9 = 9

First, let's simplify the expression inside the parentheses:

((x-14) 7+18)

Multiply 7 by (x-14):

7(x-14) + 18

Distribute the 7:

7x - 98 + 18

Combine like terms:

7x - 80

Now, let's substitute this simplified expression back into the equation:

(7x - 80):9 = 9

Divide both sides by 9 to solve for x:

7x - 80 = 81

Add 80 to both sides:

7x = 161

Divide both sides by 7:

x = 23

Therefore, the solution to the equation is x = 23.
