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