It’s going to be -18
First add 6 to both sides to get x by itself
-6x + 18 = -6
+6 +6
X + 18 = 0
Then minus the 18 giving you x = -18
Answer:

Answer:
x=3/radical2,-3/radical2,3/4
Step-by-step explanation:
By factoring you get
4x(2x^2-9)-3(2x^2-9)=(2x^2-9)(4x-3)=0
x^2=9/2, x=3/4
x=3radical2/2, -3radical2/2 , 3/4
