Step-by-step explanation:
Given :-
Sum of thrice the first and the second is 142, and four times the first exceeds the second by 138.
To Find :-
Two numbers
Solution :-
Let the first number be x
And the second number be y.
According to question
3x + y = 142 ……........….(i)
4x - y = 138 …….........…(ii)
On adding (i) and (ii),
⇒ 7x = 280
⇒ x = 40
Putting x value in eq (i)
⇒ 3x + y = 142
⇒ 3 × 40 + y = 142
⇒ y = (142 – 120) = 22
⇒ y = 22
Hence, the first number is 40 and the second number is 22.
