2x-6\leq 4x+2
Use the distributive property to multiply 2 by x-3.
2x-6-4x\leq 2
Subtract 4x from both sides.
-2x-6\leq 2
Combine 2x and -4x to get -2x.
-2x\leq 2+6
Add 6 to both sides.
-2x\leq 8
Add 2 and 6 to get 8.
x\geq \frac{8}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
x\geq -4
Divide 8 by -2 to get -4.
