Question

X:9-8=12 72:x-6=12 ............................................. ​

Answer 1

Ответ:

х = 180

х = 4

Пошаговое объяснение:

x : 9 - 8 = 12

х = (12 + 8) * 9

х = 20 * 9

х = 180

72 : х - 6 = 12

х = 72 : (12 + 6)

х = 72 : 18

х = 4

Answer 2

$\displaystyle\bf x:9-8=12\\\\x:9=20\\\\\boxed{x=180}\\\\\\72:x-6=12\\\\72:x=18\\\\x=72:18\\\\\boxed{x=4}$

Answer 3

To solve for the value of 'x' in the equations you've provided, you can follow these steps:

1. Equation 1: 9 - 8 = 12

This equation is not correct. It results in a false statement. The left side of the equation is equal to 1 (9 - 8), and the right side is equal to 12. Since 1 is not equal to 12, there is no solution for 'x' in this equation.

2. Equation 2: 72 / x - 6 = 12

To solve this equation, you can follow these steps:

a. First, add 6 to both sides of the equation to isolate the term on the left side:

  72 / x - 6 + 6 = 12 + 6

  72 / x = 18

b. Now, you want to solve for 'x,' so you need to isolate 'x' on one side. To do this, you can multiply both sides of the equation by 'x' to get 'x' out of the denominator:

  x * (72 / x) = 18 * x

  72 = 18x

c. Finally, divide both sides by 18 to solve for 'x':

  (72 / 18) = (18x / 18)

  4 = x

So, the solution for 'x' in the second equation is x = 4.
