Объяснение:

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

15+3/2x=4+2x  // *2

30+3x=8+4x

30-8=4x-3x

x=22

Answer 2

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

Step 1: Distribute the 3 on the left side of the equation to simplify it. 3(5 + x/2) = 15 + 3(x/2) = 15 + (3/2)x

Step 2: Now, the equation becomes: 15 + (3/2)x = 4 + 2x

Step 3: Isolate the term with x on one side of the equation. Let's move all terms with x to the left side by subtracting (3/2)x and 4 from both sides: (3/2)x - 2x = 4 - 15 Multiply (3/2)x by 2/2 to get a common denominator: (3/2 - 4/2)x = -11/2

Step 4: Combine the x terms on the left side: (-1/2)x = -11/2

Step 5: Now, to solve for x, divide both sides by (-1/2): x = (-11/2) / (-1/2)

Step 6: Simplify the right side by dividing the fractions: x = 11

The solution to the equation is x = 11. You can verify this by substituting x with 11 in the original equation and checking if both sides are equal.
