twice the difference of three times a number and eight
2x - 7 = -1
2x + 8 = 50
The expression "eight more than twice a number" can be written as 2x + 8, where x represents the unknown number. This expression indicates that you should first multiply the number by 2 and then add 8 to the result. For example, if the number is 5, then 2(5) + 8 = 10 + 8 = 18.
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
Eight added to twice a number is 42.Give the number the name of ' X '.8 + 2X = 42' X ' is 17.
43
The number works out as 14

twice the difference of three times a number and eight
The relevant expression (not equation) is:2*(n + 8) - 4 or2n + 8 - 4
Twice a number minus two giving us the answer as eight is number 5.
2x/8; x = the number
"the sum of 2" and "twice" "a number" "is" "36"2+2x=36 â–
One number is eight more than twice another if their difference is 25. The larger number is 42
2n + 3
It is the equation W = 2n + 5.
