Answer :
let's assume the original number to be x
now, according to question :
- 2x + 7 = 5
- 2x = 5 - 7
- 2x = - 2
- x = -2 ÷ 2
- x = -1
So, the original number was -1
Answer:
-1
Step-by-step explanation:
Solution:-
Let the number be x
So, the equation will be
- 2x +7 = 5
- 2x = 5-7
- 2x = -2
- x = -2/2
- x = -1
Verification:-
- 2x +7 = 5
- 2(-1) + 7 = 5
- -2 +7 = 5
- 5 = 5
[Thus, the original number is -1.]
