Answer 11

the difference of eight and five times a number is the same as the sum of the number and negative four. find the number.

start with
difference of eight and 5 times a number

the *5 times a number* means 5*x or just 5x
(if they don't tell us what the number is, we name it "x")

we now have
difference of eight and 5x
difference of 8 and 3 (for example) means 8 - 3

difference of eight and 5x
becomes
difference of 8 and 5x
and finally
8-5x

Answer 12

so far we changed
the difference of eight and five times a number is the same as the sum of the number and negative four. find the number.

to
8 - 5x is the same as the sum of the number and negative four

*is the same as* becomes an equal sign

8-5x = the sum of the number and negative four

the sum of the number and negative four becomes
sum of x and -4
sum means add: x+ -4

now we have
8-5x = x+ -4

now you use algebra to solve for x
