Given :-
- 3x + 5 = 10(x + 5)
To Find :-
- The value of x.
Solution :-
Given that, 3x + 5 = 10(x + 5)
=> 3x + 5 = 10(x + 5)
=> 3x + 5 = 10x + 50
=> 3x - 10x = 50 - 5
=> -7x = 45
=> x = -45/7
Hence,
- The value of x is -45/7.
Alternative form :-
- x = -6.428571
Verification :-
=> 3x + 5 = 10(x + 5)
[ Put x = -45/7 ]
=> 3(-45/7) + 5 = 10(-45/7 + 5)
=> -135/7 + 5 = 10(-10/7)
=> -100/7 = -100/7
Hence Verified !!
