Question
Solve the following by using the method of substitution
Y= 5X-1
Y=
Hint:
find x by substituting y (in terms of x) in the equation and find y by substituting value of x in the equations .
The correct answer is: x = 1 ; y = 4
Ans :- x = 1 ; y = 4
Explanation :-
⇒ y = 5x - 1 — eq 1
Step 1 :- find x by substituting y = 5x -1 in eq 2.
⇒ 10x + 3x = 11 + 2 ⇒ 13x = 13
⇒ x =1
Step 2 :- substitute value of x and find y
⇒ y = 5x – 1 ⇒ y = 5 (1) -1
∴ y = 4
∴ x = 1 and y = 4 is the solution of the given pair of equations.
