Algebra Examples
5-x>x+15−x>x+1
Step 1
Step 1.1
Subtract xx from both sides of the inequality.
5-x-x>15−x−x>1
Step 1.2
Subtract xx from -x−x.
5-2x>15−2x>1
5-2x>15−2x>1
Step 2
Step 2.1
Subtract 55 from both sides of the inequality.
-2x>1-5−2x>1−5
Step 2.2
Subtract 55 from 11.
-2x>-4−2x>−4
-2x>-4−2x>−4
Step 3
Step 3.1
Divide each term in -2x>-4−2x>−4 by -2−2. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.
-2x-2<-4-2−2x−2<−4−2
Step 3.2
Simplify the left side.
Step 3.2.1
Cancel the common factor of -2−2.
Step 3.2.1.1
Cancel the common factor.
-2x-2<-4-2
Step 3.2.1.2
Divide x by 1.
x<-4-2
x<-4-2
x<-4-2
Step 3.3
Simplify the right side.
Step 3.3.1
Divide -4 by -2.
x<2
x<2
x<2
Step 4
The result can be shown in multiple forms.
