Answer:
We have the equation,

i.e. 
i.e. 
It is required to find a system of equations having infinite solutions.
We know that,
'When the equations are dependent or their graphs are same, the system of equations has infinite number of solutions'.
So, we can take any equation having same graph as that of
.
Let, us take 
So, from the graph of these equations below, we get the system of equations having infinite solutions as,
and
.

Answer:-3.4
Step-by-step explanation:
Answer with explanation:
The equation of two planes are
1.→y +2 z=10
2.→x+y=11
To find the point of Intersection of two planes
let,→ y=t
→2 z=10 - t
10 -2 z=t
→x=11 -t
11 -x=t
So,Writing equation of line which is intersection of two planes
→ 11 -x = y= 10-2 z=t

---------------------------------(1)
⇒Putting , x=0, y=0 and z=0 in the above equation ,to find the point Closest to Origin which will be
=(11, 0, 10)
