Question

If 4 is subtracted from twice a number the result is 10 less than the number

Answer 1

First we can make an equation out of this statement. 2x-4=x-10 and now we will solve it 2x-4=x-10 2x-x=-10+4 X=-10+4=-6

Answer 2

let's take another look at the question:
If 4 is subtracted from twice a number the result is 10 less than the number.
let x = the number
"if 4 is subtracted from" is the same as
-4
"from twice a number" is the same as
2x
so put them together,
2x-4
"the result is"
=
2x-4=
10 less than
-10
the number
x
2x-4=x-10
now we find x
subtract x from both sides to get
x-4=-10
add 4 to both sides to get
x=-6
to check, plug in the value of x into the original equation
