Respuesta :
3(8 – 4x) < 6(x – 5)?- 12x + 24 < 6x - 30
- 12x - 6x < - 30 - 24
- 18x < - 54 .(- 1)
18x > 54
x > 54/18
x > 3
- 12x - 6x < - 30 - 24
- 18x < - 54 .(- 1)
18x > 54
x > 54/18
x > 3
we have
[tex]3(8-4x)<6(x-5)[/tex]
Eliminate the parenthesis
[tex]24-12x<6x-30[/tex]
Group terms that contain the same variable, and move the constants to the opposite side of the inequality
[tex]24+30<6x+12x[/tex]
[tex]54<18x[/tex]
Divide by [tex]18[/tex] both sides
[tex]54/18<x[/tex]
[tex]3<x[/tex]
rewrite the inequality
[tex]x>3[/tex]
the solution is the interval-------> (3,∞)
