D is the answer if you plug in each x from (x,y) sets the ys are correct
(-3, -26),(-1, -12),(3,16)
7x-5
7×-3=-21-5=-26 true
7×-1=-7-5=-12 true
7×3=21-5=16 true
Answer:
The solution of the given two linear equations
x = 1 and y =1
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
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
<u><em>Step(ii):</em></u>-
substitute y =1 in equation (i) , we get
4 x + 5 y = 9
4 x + 5 = 9
4 x = 4
x =1
<u><em>Final answer:</em></u>-
<em>The solution of the given two linear equations are</em>
<em>x = 1 and y =1</em>
