-2x-3 > 4x+7 .... subtract 7 from both sides, you get...
-2x-10 > 4x ..... then add 2x to both sides, and you get...
-10 > 6x ...... multiply both sides by 1/6....
-10/6 > x ..... flip it around and reduce....
-5/3 > x OR x < -5/3
x is less than or equal to -5/3
You can double check your answer. Pick a number less than x, such as -2 (which is less that -5/3). Plug it in. You get...
-2(-2) - 3 = 4-3 = 1
4(-2) + 7 = -8+7 = -1
and 1 is greater than -1, so it works!

for each (>) sign remember the (equal to bar) underneath it
-2x-3 > 4x+7 subtract 7
-2x-10 > 4x add 2x
-10 > 6x divide by 6
-10/6 > x
-5/3 > x
so x is LESS THAN OR EQUAL to -5/3

It depends on the value of x.
If x greater or equal than 5/3 then -2x-3 is greater or equal than 4x+7
You only have to solve as a regular equation, but take care of change the signs (+ / -) when multiply or divide by a negative number.

-2x - 3 >(or equal to) 4x + 7
(breaks down to)
6x+ 7 < -3
(breaks down to)
6x < -10
(breaks down to)
x < 5/3
X equals neg 5 thirds.
