i gotchu bro.
you want x to be by itself alright?
so move all the x to the left and all the rest to the right.
-19x-1=-12x+34
+12x +12x
-----------------------
-7×-1=34
NOW you gotta get this -1 to the right side. Always keep variables to the left such as the x
so do
-7x-1=34
+1 +1
----------------
-7x=35
Now, simply get x alone. since this is a NEGATIVE 7, divide by NEGATIVE 7 by both sides
-7x=35
÷-7 ÷-7
------------
x=5
you got this bro good luck thats the answer
