Question

If x represents a number then write an expression for a number that is eight less than twice the value of x.

Answer 1

2x-1

have a nice day

Answer 2

Twice the value of x is 2x, because it’s x with another x added on top (x + x = 2x)

Eight less than that is 2x - 8. That’s because you are taking away 8 from 2x (less than = subtraction).

Therefore your final expression is 2x - 8.
