1. Writing expressions with two terms

2. 6 more than 5 times a number x
Writing algebraic expression that involves two terms
Example 1:- 6 more than 5 times a number x
Lets look for phrases in the sentence for which we can already form expression and convert it into algebraic expression.
6 more than 5 times a number x +6 5x
5x + 6

3. 4 times the sum of number y and 7
Example 2: times the sum of number y and 7.
Step1:- Lets look for phrases in the sentence for which we can already form expression and convert it into algebraic expression.
4 times the sum of number y and 7
Expression of the form a+b or a-b include them in bracket x4
(y+7)
4 x (y + 7)
In algebra for representing multiplication we use ‘.’ symbol)
4 . (y + 7)

4. 5 less than the product of 3 and a number w
Example 3:- 5 less than the product of 3 and a number w
Step1:- Lets look for phrases in the sentence for which we can already form expression and convert it into algebraic expression.
5 less than the product of 3 and a number w -5 3w
3w - 5

5. twice the difference between a number z and 9.
Example 4:- twice the difference between a number z and 9.
Step1:- Lets look for phrases in the sentence for which we can already form expression and convert it into algebraic expression.
twice the difference between a number z and 9.
Expression of the form a+b or a-b include them in bracket
(z - 9) x2
2x (z - 9)
In algebra for representing multiplication we use ‘.’ symbol)
2. (z - 9)

6. Try these 10 more than 5 times a number z
Three times the difference between a number h and 7.
10 less than the product of 7 and a number m
