Answer:
x > 6
Step-by-step explanation:
1.) Distribute - 3 through the parenthesis
7x-3(4x-8)<6x+12-9x
7x-12x+24<6x+12-9x
2.) Then collect like terms
7x-12x+24<6x+12-9x
7x-12x+24<-3x+12
7x-12x+24<-3x+12
-5x+24<-3x+12
3.) Move the <u>variable</u> to the left and change the sign
-5x+24<-3x+12
-5x+3x+24<12
4.) Move the <u>constant</u> to the right and change it's sign
-5x+3x+24<12
-5x+3x<12-24
5.) Collect like terms
-5x+3x<12-24
-2x<12-24
6.) Calculate the difference
-2x<-12
7.) Divide both sides by -2 and flip the inequality sign
-2x<-12
x>6
