Question

7 < 3 - 2x

Answer 1

steps:
1) subtract 3 from both sides
2) divide by (-2)
|--> this is an inequality (dividing by negative means flip the inequality sign)

x < -2 is what i got.

Answer 2

\[2x<3-7\]\[2x<-4\]\[x<-2\]

Answer 3

minus 3 from both sides

4<-2x

divide by -2 ,but when dividing by a negative you switch the inequality
so

-2>x

Answer 4

or x<-2
