Sagot :
We can start this equation off by doing the inverse operation for each sides. We add 9 to both sides in order to get rid of the -9 term to get:
[tex]-11x = 77[/tex]
We now divide both sides by -11 in order to "isolate" our x variable to get:
[tex]x = -7[/tex]
Answer:
x=-7
Step-by-step explanation:
-11x=68+9
-11x=77
divide both sides by -11
x=-7
