Answer 2

1. Equation :– pq (p + 3) + r.

Given values :– p = 2, q = 3 and r = –1.

Now, put all the given values of p, q and r in the given equation.

↣ (2) (3) (2 + 3) + (–1)

Now, open the brackets.

↣ 6 × 5 – 1

↣ 30 – 1

↣ 29

━━━━━━━━━━━━━━━━━━━━━━

2. Equation :– 12p (q – r).

Given values :– p = 1, q = 4 and r = –2

Now, put the given values of p, q and r in the given equation.

↣ 12(1) [ 4 – (–2) ]

Open both brackets.

↣ 12 (4 + 2)

Again, open a bracket.

↣ 12 × 6

↣ 72

━━━━━━━━━━━━━━━━━━━━━━

3. Equation :– 1 – x + y.

Given Values :– x = –2 and y = –7

Now, put the given values of x and y in the given equation.

↣ 1 – (–2) + (–7)

Open both the brackets.

↣ 1 + 2 – 7

↣ 3 – 7

↣ – 4

━━━━━━━━━━━━━━━━━━━━━━

4. Equation :– (a – b)(b – c).

Given values :– a = 2, b = –5 and c = –8.

Now, put the given values of a, b and c in the given equation.

↣ [ (2) – (–5) ] [ (–5) – (–8) ]

Open both small brackets.

↣ [2 + 5] [–5 + 8]

Now, open both large brackets.

↣ 7 × 3

↣ 21

━━━━━━━━━━━━━━━━━━━━━━

5. Equation :– 8 (m + n) – mn.

Given values :– m = 2 and n = 5.

Now, put the given values of m and n in the given equation.

↣ 8 (2 + 5) – (2) (5)

Open both brackets.

↣ 8 × 7 – 10

↣ 56 – 10

↣ 46
