Question

8:(х-1/6)=12 б) 9:(1/10)=15

Answer 1

Второе не решается, оно неверно записано. Там может «х» пропущен.

Answer 2

To solve the equations:

a) 8 * (x - 1/6) = 12

We can begin by simplifying the equation:

8x - 8/6 = 12

To further simplify, we convert the fraction 8/6 to 4/3:

8x - 4/3 = 12

To isolate the variable, we can add 4/3 to both sides of the equation:

8x = 12 + 4/3

To add 12 and 4/3, we need to find a common denominator, which is 3:

8x = 36/3 + 4/3

Combining the fractions:

8x = 40/3

Finally, we divide both sides of the equation by 8 to solve for x:

x = (40/3) / 8

x = 40/3 * 1/8

Simplifying the multiplication:

x = 40/24

x = 5/3

Therefore, the solution to the equation 8 * (x - 1/6) = 12 is x = 5/3.

b) 9 / (1/10) = 15

When dividing by a fraction, we can multiply by its reciprocal. The reciprocal of 1/10 is 10/1:

9 * (10/1) = 15

Simplifying the multiplication:

90 = 15

This equation is not true since 90 is not equal to 15. Therefore, there is no solution to the equation 9 / (1/10) = 15.
