Answer 1

Ответ:

9/12y-6/12=7/12(привели к общему знаменателю)

9/12y=7/12+6/12

9/12y=13/12

y=13/12:9/12

y=13/12•12/9

y=13/9

y=1 4/9

Answer 2

Solving the Equation 3/4u - 2/3 = 7/12

To solve the equation 3/4u - 2/3 = 7/12, we can follow these steps:

1. Add 2/3 to both sides of the equation to isolate the term with u on one side. 2. Find the common denominator for the fractions to simplify the equation. 3. Simplify the equation by performing the necessary arithmetic operations. 4. Solve for u to find the value of u that satisfies the equation.

Let's proceed with these steps to solve the given equation.

Step 1: Add 2/3 to Both Sides

We add 2/3 to both sides of the equation to isolate the term with u on one side.

Step 2: Find the Common Denominator

To simplify the equation, we need to find the common denominator for the fractions involved. The common denominator for 4, 3, and 12 is 12.

Step 3: Simplify the Equation

Now, let's simplify the equation by performing the necessary arithmetic operations.

The equation becomes: 3/4u = 7/12 + 2/3

Step 4: Solve for u

After simplifying the equation, we can solve for u to find the value that satisfies the equation.

Let's calculate the right-hand side of the equation first.

7/12 + 2/3 = 7/12 + 8/12 = 15/12 = 5/4

So, the equation becomes: 3/4u = 5/4

To solve for u, we can multiply both sides by the reciprocal of 3/4, which is 4/3.

(4/3) * (3/4u) = (4/3) * (5/4) u = 5/3

Conclusion

The solution to the equation 3/4u - 2/3 = 7/12 is u = 5/3.
