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 If you have any further questions, just ask me
