You can put this solution on YOUR website! IF -2x<14, is x<-7? why or why not
-2x < 14
To find x, we need to divide both sides by -2. Notice that we must divide by the coefficient of x, which in this case is a nagative number. When we divide by a negative number, the sign of the inequality must be reversed.
In other words, < becomes >.
-2x < 14
x > 14/-2
x > -7
To make the above inequality a true statement, any value chosen for x must be GREATER THAN -7.
