Answer:
The solution of the given two linear equations
x = 1 and y =1
Explanation:
Step(i):-
Given 4 x + 5 y = 9 ..(i)
- 11 x - 9 y = - 20 ...(ii)
Multiply 11 by (i) and multiply 4 by (ii)
44 x + 55 y = 99 ...(a)
- 44 x - 36 y = -80...(b)
Adding above equations (a) and (b) , we get
19 y = 19
y = 1
Step(ii):-
substitute y =1 in equation (i) , we get
4 x + 5 y = 9
4 x + 5 = 9
4 x = 4
x =1
Final answer:-
The solution of the given two linear equations are
x = 1 and y =1
