Answer 1

Answer:

1 st one Will be infinitely many Solution because

y=3x+5

Thus means for any value of X you will have A corresponding Value of Y So you can have infinite Values of X therefore Infinite value of Y.

Ans Infinitely many solution.

2) 2x+y=7

X=3 Y =1

X=2 Y=3

x= 1 .Y=7

X=4.Y= -1( Minus 1)

these are the 4 solutions for the equation 2x+Y=7

2(3) X= 4y

this means X-4y=0

Now solutions

X=4 .Y=1

X=-4( Minus 4) Y =-1( minus 1)

X= 2 Y = 1/2 ( Half )

X=-2( Minus 2) And Y = -1/2( Minus half)

You can check the solutions But putting the value of X and Y in the corresponding equations.

For example

2x+Y=7

let's take One of the solution I gave

X=3 Y=1

So now put the values of X and Y in the equation 2x+Y=7

2(3) +1

6+1=7 Hence LHS= RHS hence X=3 and Y=1 is the solution of the equation.....Hope You understood

Hope it helps
