-10x+4.
5x-7x is -2.
-2x-8x is -10x.
you cannot simplify the 4
alternatively, you could write -10x+4 as
-2(5x-2)
If you divide 12 by 384 and put it in a calculator you get 32.this means 12 goes 32 times in 384
We know that there are 3 people paying you and you have 92. They are paying you 2 a day. that means we need to multiply 3*2=6 and 6*16=96
What is 92+96=188
That means you will have 188 coins in 16 days
Hope this helped!
