2.5 - 1.2x < 6.5 - 3.2x?

Answer: x<2 or xϵ (-∞; 2)

Step-by-step explanation:

Add + 3.2x to both sides of inequality:

2.5-1.2x+3.2x<6.5-3.2x+3.2x

2.5+2x<6.5

Deduct 2.5 from both sides of inequality:

2.5-2.5+2x<6.5-2.5

2x<4

Divide both sides of inequality by 2

2x/2<4/2

x<2 or xϵ (-∞; 2) (the answer can be written in 2 ways)
