Ответ 9

Пошаговое объяснение:

25-(x*30+360):70=16

(x*30+360):70=25-16

(x*30+360):70=9

(x*30+360)=70*9

x*30+360=630

х*30=630-360

х*30=270

х=270:30

х=9

Answer 2

Let's solve the equation step by step:

1. First, simplify the expression inside the parentheses:

25 - (x * 30 + 360) / 70 = 16

2. Next, subtract 25 from both sides to isolate the expression on the left side:

-(x * 30 + 360) / 70 = 16 - 25

3. Simplify the right side:

-(x * 30 + 360) / 70 = -9

4. Multiply both sides by -70 to get rid of the fraction:

-70 * (-(x * 30 + 360) / 70) = -9 * (-70)

5. The -70 on the left side cancels out with the -70 on the right side:

-(x * 30 + 360) = 630

6. Now, distribute the negative sign on the left side:

-x * 30 - 360 = 630

7. Add 360 to both sides to isolate the term with x:

-x * 30 = 630 + 360

8. Simplify the right side:

-x * 30 = 990

9. Finally, divide both sides by -30 to solve for x:

x = 990 / -30

x = -33

So, the solution to the equation is x = -33.
