The simplified expression is-
The value is-
AND
123−2x−3x+7 for x=5
The simplified expression is-
The value is-

Answer 1

Answer:

see below

Step-by-step explanation:

3x + 7x − 28 + 31 − 8x

Simplified:

  2x + 3

Value when x = 2043:

  2x + 3  

  2(2043) + 3

  4086 + 3

  = 4089

123 − 2x − 3x + 7

Simplified:

  -5x + 130

Value when x = 5:

  -5x + 130

  -5(5) + 130

  -25 + 130

  = 105
