3(-4x+5)=12 (Divide by 3 on both sides)
-4x+5=4 (Add -5 to both sides)
-4x=-1 (Divide by -4 on both sides)
x=1/4
Check:
3(-4(1/4)+5)=12
3(-1+5)=12
3(4)=12
So, your final answer is x=1/4
F=??
4 vertices mean V=4
6 edges mean E=6
4-6+F=2
-2+F=2
F=4
Answer: HCF and LCM of two numbers can be same only if two numbers are equal. Hence their difference will be zero
