Which expression correctly represents '5 less than $x$ '?

Class 6AlgebraAlgebra

Step-by-Step Solution

'5 less than

x

' means start from

x

and take away 5:

x - 5

. Note it is NOT

5 - x

Answer: A)

x - 5

To evaluate an expression, **substitute** a value for the variable and compute. If

x = 5

, then

2 x + 3

becomes

2 \times 5 + 3 = 10 + 3 = 13

. The same expression with

x = 0

gives

2 \times 0 + 3 = 3

. Practise substituting — it is the bridge between an algebraic expression and a real number.

Don't just memorise the answer — build a daily practice habit.
