Isolate the variable and solve. To isolate x, we must eliminate the negative sign in front of the x. Because -x means –1x, we can do this by multiplying (or dividing) both sides of the inequality by -1. We are multiplying by a negative number. Thus, we must reverse the direction of the inequality symbol. (-1)(-x) = (-1)(-14) Multiply both sides by -1 and change the sense of the inequality. x < 14 Simplify.

Isolate the variable and solve. To isolate x, we must eliminate the negative sign
in front of the x. Because -x means –1x, we can do this by multiplying (or dividing)
both sides of the inequality by -1. We are multiplying by a negative number. Thus, we
must reverse the direction of the inequality symbol.
(-1)(-x) = (-1)(-14)
Multiply both sides by -1 and change the
sense of the inequality.
x < 14
Simplify.
