3\left(x-3\right)\leq 2\left(x-6\right)
Multiply both sides of the equation by 6, the least common multiple of 2,3. Since 6 is positive, the inequality direction remains the same.
3x-9\leq 2\left(x-6\right)
Use the distributive property to multiply 3 by x-3.
3x-9\leq 2x-12
Use the distributive property to multiply 2 by x-6.
3x-9-2x\leq -12
Subtract 2x from both sides.
x-9\leq -12
Combine 3x and -2x to get x.
x\leq -12+9
Add 9 to both sides.
x\leq -3
Add -12 and 9 to get -3.
