\frac{3\left(x-4\right)}{2}+3\geq x
Express 3\times \frac{x-4}{2} as a single fraction.
\frac{3x-12}{2}+3\geq x
Use the distributive property to multiply 3 by x-4.
\frac{3}{2}x-6+3\geq x
Divide each term of 3x-12 by 2 to get \frac{3}{2}x-6.
\frac{3}{2}x-3\geq x
Add -6 and 3 to get -3.
\frac{3}{2}x-3-x\geq 0
Subtract x from both sides.
\frac{1}{2}x-3\geq 0
Combine \frac{3}{2}x and -x to get \frac{1}{2}x.
\frac{1}{2}x\geq 3
Add 3 to both sides. Anything plus zero gives itself.
x\geq 3\times 2
Multiply both sides by 2, the reciprocal of \frac{1}{2}. Since \frac{1}{2} is positive, the inequality direction remains the same.
x\geq 6
Multiply 3 and 2 to get 6.
