4x-3<6x+3
Use the distributive property to multiply 3 by 2x+1.
4x-3-6x<3
Subtract 6x from both sides.
-2x-3<3
Combine 4x and -6x to get -2x.
-2x<3+3
Add 3 to both sides.
-2x<6
Add 3 and 3 to get 6.
x>\frac{6}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
x>-3
Divide 6 by -2 to get -3.
