Question 262405
The basic goal of indirect proofs is you assume the opposite of what you are trying to prove as true and try to get some kind of contradiction. Lets see where this takes us . . . 
STATEMENT #1: x <= 3
REASON #1: indirect assumption
STATEMENT #2: -4X + 2 < -10
REASON #2: Given
STATEMENT #3: -4x + 2 - 2 < -10 - 2
REASON #3: subtraction property of equality
STATEMENT #4: -4x < -12
REASON #4:additive inverse property
STATEMENT #5: -4x* (-1/4) > -12 * (-1/4)
REASON #5:multiplication property of equality
STATEMENT #6: x > 3
REASON #6:multiplicative inverse property
Notice we have a contradiction between step #1 and step #6. Since we have a contradiction, our assumption of statement #1 was false and therefore,
x > 3.
