Solve,
12 - 3x < 4x - 2
Rearranging,
12 + 2 < 4x + 3x
Simplifying,
14 < 7x
Switch around,
7x > 14
Simplifying,
x > 14/7
x > 2 (ans)

Recall, the steps for solving a linear equation.
1. Use the distributive property to get rid of any parenthesis.
2. If there are any fraction, multiply each term of the equation by the common denominator of the
of all the fractions.
3. On each side of the equation, combine like terms.
4. Move terms across the equal sign by changing to the opposite sign so that the variable term = number.
5. Divide both sides of the equation by the coefficient of the variable term.

12-3x<4x-2
-3x<4x-14
-7x<-14
x<2
Whatever you do on one side of the equation must be done on the other side, exactly the same way. Remember, your first goal is to get the unknown (in this case the 'x') all by itself, first.

Its simple,
12-3x<4x-2
so, 12+2<4x+3x
so, 14<7x
or, 7x>14
or, x>2
Hope you understood.

12-3x<4x-2
move the -2 left, making it 14-3x<4x
move the -3x left, making it 14<7x
divide 14 by 7=2
answer: x>2

12-3x < 4x-2
12 < 7x -2
14 < 7x
2 < x
or
12-3x < 4x-2
12-7x < -2
-7x < -14
x > 2 (when you divide by a negative, you switch the sign)
