we have
[tex]2.5-1.2x < 6.5-3.2x[/tex]
Group terms that contain the same variable, and move the constants to the opposite side of the inequality
[tex]3.2x-1.2x < 6.5-2.5[/tex]
Combine like terms
[tex]2x < 4[/tex]
[tex]x < 2[/tex]
The solution is the interval-------> (-∞,2)
All real number less than [tex]2[/tex]
The answer in the attached figure
