Question 1 :
Simplify :
-2(x - 9) + 4 (x + 7)
Question 2 :
Simplify :
6x - 3(2 - 3x)
Question 3 :
Simplify :
- 6 + 9 (8 - 2b)
Question 4 :
Simplify :
4(x - 10) - 6(x - 4)
Question 5 :
Simplify :
10(9 + 8x) - 6(7x + 9)
Question 6 :
Simplify :
7(1 + 10p) + 8(1 + 6p)
Question 1 :
Simplify :
-2(x - 9) + 4 (x + 7)
Solution :
In order to simplify the above expression, we need to use the distributive property.
= −2(x − 9) + 4 (x + 7)
= -2x + 18 + 4x + 28
= -2x + 4x + 18 + 28
= 2x + 46
Question 2 :
Simplify :
6x - 3(2 - 3x)
Solution :
In order to simplify the above expression, we need to use the distributive property.
= 6x − 3(2 − 3x)
= 6x − 6 + 9x
= 6x + 9x - 6
= 15x - 6
Question 3 :
Simplify :
- 6 + 9 (8 - 2b)
Solution :
In order to simplify the above expression, we need to use the distributive property.
= −6 + 9 (8 − 2b)
= -6 + 72 - 18b
= 66 - 18 b
Question 4 :
Simplify :
4(x - 10) - 6(x - 4)
Solution :
In order to simplify the above expression, we need to use the distributive property.
= 4(x − 10) − 6(x − 4)
= 4x - 40 - 6x + 24
= 4x - 6x - 40 + 24
= -2x - 24
Question 5 :
Simplify :
10(9 + 8x) - 6(7x + 9)
Solution :
In order to simplify the above expression, we need to use the distributive property.
= 10(9 + 8x) − 6(7x + 9)
= 90 + 80 x - 42x - 54
= 90 - 54 + 80 x - 42x
= 36 + 38x
Question 6 :
Simplify :
7(1 + 10p) + 8(1 + 6p)
Solution :
In order to simplify the above expression, we need to use the distributive property.
= 7(1 + 10p) + 8(1 + 6p)
= 7 + 70 p + 8 + 48 p
= 7 + 8 + 70 p + 48 p
= 15 + 118 p
