Answer:
4
Step-by-step explanation:
-9-(12-3x)=-9-1*(12)-1*(-3)=-9-12+3x=-21+3x=3(x-7)
If you are just simplifying it it would be 6x because it's 5x plus one more x but if you are trying to find x then I have no idea
I hope this helps you
log6 [x. (2x-7)]=log6 (6^2)
x. (2x-7)=36
2x^2-14x-36=0
2x +4
x -9
(2x+4)(x-9)=0
x= -2
x=9
