Answer 2

4*((х+2):2+30)+(25*4-80)=180

4*((х+2):2+30)+20=180

4*((х+2):2+30)=180-20

4*((х+2):2+30)=160

((х+2):2+30)=160:4

(х+2):2+30=40

(х+2):2=40-30

(х+2):2=10

х+2=10*2

х+2=20

х=20-2

х=18

Ответ:18

Answer 3

Let's solve the given equation step-by-step:

1. Replace 'х' with 'x' for clarity: 4*((x+2)/2+30)+(25*4-80)=180

2. Simplify the expression within the parentheses first: (x+2)/2 + 30 = (x/2) + 1 + 30 = (x/2) + 31

3. Now the equation becomes: 4*((x/2) + 31) + (25*4 - 80) = 180

4. Next, distribute the 4 on the left side: 4*(x/2) + 431 + (254 - 80) = 180

5. Simplify further: 2x + 124 + (100 - 80) = 180

6. Continue to simplify: 2x + 124 + 20 = 180

7. Combine like terms: 2x + 144 = 180

8. Now, isolate 'x' on one side by moving 144 to the other side of the equation: 2x = 180 - 144

9. Calculate: 2x = 36

10. Finally, solve for 'x' by dividing both sides by 2: x = 36/2

11. The solution for 'x' is: x = 18

So, the value of 'x' that satisfies the equation is x = 18.
