Question

Write an inequality with the solution x ≥ 1.

Answer 1

Hello. Capri

 

Ok, here is on possibility

 

-3x   +  5  <=  -2x  +4         Adding 2x to both sides

 +2x                +2x         

   -x   +5   <=   4                 Subtracting 5 from both sides

         -5           -5

    -x         <=    -1               Multiplying by -1, LOOK AT WHAT HAPPENS TO THE SIGN OF THE INEQULITY !!!

     x          >=    1

 

There is a rule that states that if you multiply or divide an inequality by a negative number, you must switch the sign of the inequality. 

 

I hope this helps.
