Question

Simplify:
1)-70+(-23)+(-17)+(7)+(100)

2)p-3=7, using trail and error method​

Answer 1

Answer:

Simplify:

1)-70+(-23)+(-17)+(7)+(100) = -70-23-17+7+100

= -110+107

= -3

2)p-3=7

p=7+3

=10

Answer 2

Answer:

1) (-3)

2) 10

Step-by-step explanation:

1) -70+(-23)+(-17)+(7)+(100)

  -70-23-17+7+100

  -110+107

  -3

2) p - 3 = 7

   Let's Take p = 3,

   now, 3 - 3 is not equal to 7.

   Therefore, 3 is not the solution.

   So, Let's Take p = 5,

   now, 5 - 3 is not equal to 7.

   Therefore, 5 is not the solution.

   So, Let's Take p = 7,

   now, 7 - 3 is not equal to 7.

   Therefore, 7 is not the solution.

   So, Let's Take p = 10,

   now, 10 - 3 is equal to 7.

   Therefore, 10 is not the solution.
