Question

find two solutions for tge following linear equation in two variables : x - 2y = 4
please guys give me correct answer with full explanation.​

Answer 1

Answer:

ANSWER

Given equation isx+2y=4

(i) Put the value x=0 and y=2 we get

0+2×2=4

⇒4=4

Then both sides are equal then (0,2) is the solution of equation x+2y=4

(ii) Put the value x=2 and y=0 we get

2+2×0=4

⇒2



=4

Then both sides are not equal then (0,2) is not the solution of equation

x+2y=4

(iii) Put the value x=4 and y=0 we get

4+2×0=4

⇒4=4

Then both sides are equal then (4,0) is the solution of equation x+2y=4

(iv)x+2y=4

Put x=

2

,y=−3

2

we get

2

+2(−3

2

)=4

⇒

2

−3

2

=4

⇒−2



=4

Then both sides are not equal then (

2

,−3

2

) is not the solution of equation

x+2y=4

(v) Put the value x=1 and y=1 we get

1+2×1=4

⇒3



=4

Then both sides are not equal then (1,1) is not the solution of equation

x+2y=4

(vi) Put the value x=-2 and y=3 we get

−2+2×3=4

⇒4=4

Then both sides are equal then (-1,3) is the solution of equation

x+2y=4

Answer 2

Answer:

x-y=2

Step-by-step explanation:

x-2y=4

x-y=4/2

x-y=2

hence LHS NOT EQUAL TO RHS
