Final answer:
The solution to the inequality 4+2x<=4 is x<=0.
Step-by-step explanation:
To solve the inequality 4+2x<=4, we can start by subtracting 4 from both sides: 2x<= 0. Then, we divide both sides by 2 to isolate x: x<=0/2. Since any number divided by 2 is still less than or equal to zero, the solution to this inequality is x<=0.
