-2(7n-6)+n=-3-8n
multiply the bracket by -2
-2(7n)-2(-6)+n= -3-8n
-14n+12+n= -3-8n
-14n+n+12= -3-8n
-13n+12= -3-8n
Move -8n to the other side. Sign changes from -8n to 8n.
-13n+8n+12= -3-8n+8n
-5n+12= -3
move +12 to the other side
sign changes from +12 to -12
-5n+12-12= -3-12
-5n= -15
Divide by -5
-5n/-5= -15/-5
n= 3
Answer : n= 3
