Question

18+(16-x)*8=90как решить

Answer 1

Ответ:

х= 7

Пошаговое объяснение:

18 + 128- 8х = 90

146 - 8х = 90

-8х = 90 - 146

-8х = -56

х = -56:(-8)

х = 7

Answer 2

To solve the equation 18 + (16 - x) * 8 = 90, follow these steps:

Step 1: Simplify the equation. 18 + (16 - x) * 8 = 90

Step 2: Apply the distributive property to the expression (16 - x) * 8. 18 + 8 * (16 - x) = 90

Step 3: Simplify the expression within the parentheses. 18 + 128 - 8x = 90

Step 4: Move constants to one side and the variable term to the other side of the equation to isolate the variable (x). 18 + 128 - 90 = 8x

Step 5: Perform the arithmetic operations. 56 = 8x

Step 6: Solve for x by dividing both sides by 8. x = 56 / 8

Step 7: Calculate the value of x. x = 7

So, the solution to the equation is x = 7.
