Question

3x-1/8=7/4 срррооооооччччннноооооо​

Answer 1

Ответ:

х = 5/8

Пошаговое объяснение:

3х - 1/8 = 14/8

3х = 15/8

х = (15/8):3

х = 5/8

Answer 2

To solve the equation 3x - 1/8 = 7/4, you need to isolate x. Here's the step-by-step solution:

1. First, add 1/8 to both sides of the equation to get rid of the constant term on the left side:

   3x - 1/8 + 1/8 = 7/4 + 1/8

2. Simplify the left side by canceling out -1/8 and 1/8, which leaves you with:

   3x = 7/4 + 1/8

3. Now, you need to find a common denominator for the fractions on the right side. The common denominator is 8. So, rewrite 7/4 with a denominator of 8:

   7/4 = (7/4) * (2/2) = 14/8

   So, 7/4 is equivalent to 14/8.

4. Now, add 14/8 and 1/8:

   14/8 + 1/8 = 15/8

5. Now, your equation becomes:

   3x = 15/8

6. To isolate x, divide both sides by 3:

   (3x) / 3 = (15/8) / 3

7. Simplify:

   x = (15/8) / 3

8. To divide by 3, you can multiply by 1/3:

   x = (15/8) * (1/3)

9. Multiply the fractions:

   x = (15/24)

10. You can further simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3:

x = (15/3) / (24/3)

x = 5/8

So, the solution to the equation 3x - 1/8 = 7/4 is x = 5/8.
