How many terms are in the expression $4 x + 7 y - 2$ ?

Class 6AlgebraAlgebra

Step-by-Step Solution

Terms are separated by + or −. The terms here are

4 x, 7 y

, and 2. That's 3 terms.

Answer: B) 3

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.
