Question

3(3x+4)=2(4x+5)+x vxhdbdbdb​

Answer 1

Ответ:

3(3x+4)=2(4x+5)+x

9x+12=8x+10+x

9x-8x-x=10-12

0x=-2

Answer 2

To solve the equation 3(3x + 4) = 2(4x + 5) + x, follow these steps:

Step 1: Distribute the values on both sides of the equation. Step 2: Combine like terms. Step 3: Isolate the variable (x) on one side of the equation. Step 4: Solve for x.

Let's do it step by step:

Step 1: Distribute the values on both sides of the equation.

On the left side: 3(3x + 4) = 3 * 3x + 3 * 4 = 9x + 12

On the right side: 2(4x + 5) + x = 2 * 4x + 2 * 5 + x = 8x + 10 + x = 9x + 10

Now the equation becomes: 9x + 12 = 9x + 10

Step 2: Combine like terms.

In this case, there are no like terms to combine because both sides already have the same expression (9x).

Step 3: Isolate the variable (x) on one side of the equation.

To do this, we'll get rid of the 9x on the right side. We can achieve this by subtracting 9x from both sides of the equation:

9x + 12 - 9x = 9x + 10 - 9x (9x - 9x) + 12 = 10

Simplifying further, we get: 12 = 10

Step 4: Solve for x.

After completing the steps, we find that the equation leads to an inconsistency, as the statement 12 = 10 is false. Therefore, there is no solution for the equation 3(3x + 4) = 2(4x + 5) + x.
