Question

A student concluded that the inequality -3+2y<4x is equivalent to the inequality y>2x+3/2, as shown below. Describe and correct the students error

Answer 1

Explanation:

-3+2y<4x

then

2y< 4x+ 3 (add both sides with 3)

y < 2x +3/2 ( divide both sides by 2 that is positif and we do not change the sens < )

Hope you understand.
