Answer:
answer=15
Step-by-step explanation:
12 + ( 1/2x + 3) = 45
subtract 12 from each side
(1/2x + 3 = 33
subtract 3 from each side
1/2x = 30
x=15
The expression is written by the equation 1 / 2X + 3 + 12 = 45.
To write the expression: 12 more than the sum of half a number and 3 is 45 in a correctly formulated equation, the following analysis must be performed:
- 12 = is added to the remaining numbers
- The sum of half a number and 3 = main mathematical operation
- 45 = result
- 1 / 2X + 3 + 12 = 45
- 1 / 2X = 30
- X = 60
