Answer as a fraction: x = 27/8
Answer in decimal form: x = 3.375
======================================================
Work Shown:
-11x+21=-3x-6
-11x=-3x-6-21
-11x+3x = -6-21
-8x = -27
x = -27/(-8)
x = 27/8 is the answer as a fraction
x = 3.375 is the answer in decimal form
Step-by-step explanation:
The idea is to get x by itself. In step 2, I subtracted 21 from both sides. In the third step, I added 3x to both sides. This will mean the x terms are on one side, and the non x terms are on the other. After combining like terms, I divided both sides by -8 to fully isolate x.
Side note: The improper fraction 27/8 is equivalent to the mixed number 3 & 3/8
