Practice the questions given in the worksheet on addition of unlike terms. We know that, the sum of two or more like terms can be express as a single like term but in case of unlike terms we cannot add them together to express the result as a single term.

**1. Find the sum of: **

(i) 3x and 5y

(ii) 2a and 7a(iii) 9x

(iv) 8ab, 3a and 4b

(v) 2a, 5a

(vi) xy, yz and zx

**2. Add the following:**

(i) 2a, 3a and 7b

(ii) 6a, 4a and 8ab

(iii) 3p, 5q and 11q

(iv) 3ab, 5ba and 7b

(v) 25pq, 35qp and 15pr

(vi) 7x**3. Simplify the
following:**

(i) -3a and 7b

(ii) 5a and -4b

(iii) -x(iv) xy and -yz

(v) –abc and ab

(vi) m**4. Evaluate the
following:**

(i) 6a – b – 5a

(ii) 12ab – 3ab + 5bc

(iii) x – 3x + 5y + 10x

(iv) 4a + 3b – 2a – b

(v) 5mn + 6nm + 13

(vi) 9abc – 11ab + 39abc

**5.** What is the
sum of -7xy and -11x?

**6.** Sam has **x** number of marbles and Ron has **y** number of marbles. How many marbles
both of them has altogether?
