3+3x-2\left(2x+1\right)\leq 1
Use the distributive property to multiply 3 by 1+x.
3+3x-4x-2\leq 1
Use the distributive property to multiply -2 by 2x+1.
3-x-2\leq 1
Combine 3x and -4x to get -x.
1-x\leq 1
Subtract 2 from 3 to get 1.
-x\leq 1-1
Subtract 1 from both sides.
-x\leq 0
Subtract 1 from 1 to get 0.
x\geq 0
Product of two numbers is ≤0 if one is ≥0 and the other is ≤0. Since -1\leq 0, x must be ≥0.
