2x 10x 5 non-negative integer solutions x=0,1,2,3,4,5 There are 6 in total.

The negative integer solution of inequality 3(x+2) 4+2x is -1 and -2, and the non-positive integer solution is -2 and -1,0.

Solution: 3(x+2) 4+2x

3x+6≥4+2x

3x-2x≥4-6

x -2 so the negative integer solution of inequality 3 (x+2) 4+2x is -1 , -2 , and the non-positive integer solution is -2 , -1 , 0.

3（x+2）≥4+2x

Deparentheses: 3x+6 4+2x

Shift: 3x-2x 4-6

Merge similar items: x -2

Because x is a negative integer, x=-2 or -1;

Because x is a non-positive integer, x = -2 or -1 or 0

From the meaning of the title.

3x+6≥4+2x

Simplifying the equation. x+2≥0

x -2 so the negative integer solution is -2, -1

Non-positive integers are solved as 0 (-2, -1 can also be counted).

The negative integer solution of inequality 3(x+2) 4+2x is -2, -1 When x -2, the value of the algebraic equation is positive; When x, the value of the algebraic formula is negative; When x, the value of the algebraic formula is a non-negative number Test point: integer solutions to unary inequalities Topic: Calculation problems Analysis:

Solve the inequality 3(x+2) 4+2x to obtain the negative integer solution;

The algebraic formula is a positive number, that is, the value of the algebraic formula is greater than 0, it is a negative number, that is, it is less than 0, and it is a non-negative number, that is, it is less than or equal to 0, list the inequalities, and solve it Answer: Solution: Solve the inequality 3(x+2) 4+2x to get:

x -2, then the negative integer solution of the inequality is: -2, -1;

According to the meaning of the question: 0, the solution is: x -2;

0, solution: x;

0, solution: x;

So the answer is: -2, -1;x＞-2； ；Comments: This problem mainly examines the solution of inequality, and finding the solution set is the key to solving this problem The solution of inequality should be based on the basic properties of inequality

Negative integers are solved as -2, -1

Non-positive integers are solved as

3(x+2)≥4+2x
