7\left(x-2\right)+7-2\left(2x-3\right)+1\leq 0
Multiply both sides of the equation by 14, the least common multiple of 2,7,14. Since 14 is positive, the inequality direction remains the same.
7x-14+7-2\left(2x-3\right)+1\leq 0
Use the distributive property to multiply 7 by x-2.
7x-7-2\left(2x-3\right)+1\leq 0
Add -14 and 7 to get -7.
7x-7-4x+6+1\leq 0
Use the distributive property to multiply -2 by 2x-3.
3x-7+6+1\leq 0
Combine 7x and -4x to get 3x.
3x-1+1\leq 0
Add -7 and 6 to get -1.
3x\leq 0
Add -1 and 1 to get 0.
x\leq 0
Product of two numbers is ≤0 if one is ≥0 and the other is ≤0. Since 3\geq 0, x must be ≤0.
