Answer 1

Ответ:

Пошаговое объяснение:

5*(810/9-x*3)=315

90-3х=315:5

90-3х=63

-3х=63-90

-3х=-27

х=-27:(-3)

х=9

Answer 2

Ответ:

9

Пошаговое объяснение:

5*(810/9-x*3)=315

5*(90-3x)=315

раскроем скобки

450-15x=315

переносим известное вправо, неизвестное влево.

-15x=315-450

-15x=-135

сокращаем на -15

-15x=-135 |:-15

x=9

Answer 3

To solve the equation 5*(810/9 - x*3) = 315, follow these steps:

Step 1: Simplify the expression on the left-hand side (LHS) of the equation: 5*(810/9 - x3) = 5(90 - 3x)

Step 2: Distribute the 5 to both terms inside the parentheses: 5*(90 - 3x) = 450 - 15x

So, the equation becomes: 450 - 15x = 315

Step 3: Isolate the variable term (in this case, -15x) by moving the constant term (450) to the other side of the equation: 450 - 15x - 450 = 315 - 450 -15x = -135

Step 4: Solve for x by dividing both sides by -15: x = -135 / -15 x = 9

Therefore, the value of x that satisfies the equation is x = 9.
