12 - ( 4х - 18 ) = ( 36 + 4х ) + ( 18 - 6х )

Question

12 - ( 4х - 18 ) = ( 36 + 4х ) + ( 18 - 6х )

Answer 1

12-(4х-18) = (36+4х) + (18 - 6х)
12 - 4х + 18 = 36х+4х + 18 - 6х
12+18-18 = 36х +4х - 6х + 4х
38х = 12
х= 6/19

Answer 2

12-(4х-18)=(36+4х)+(18-6х)
12-4х+18=36+4х+18-6х
30-4х=54-2х
-4х+2х=54-30
-2х=24
х=-12
