The system ax+by=c has the solution (2,-3) where dx + ey=f

a,b,c,d,e, and f are non zero real numbers. select all the systems of equations with the same solution.

Answer with explanation:

It is given that, the two set of equations,

  Ax+By=C ,(1)

  D x + E y=F(2)

has the solution (2,-3).

→→Equation (1) - Equation (2)

(A-D)x + (B-E)y=C-F(3)

And, Second equation is,  D x + E y=F(4)

Equation (3) and (4), when solved , will produce the same solution, as given equation.

→→→Multiply equation (1), by 2 and it to equation (2)

2 A x +2 B y +D x + E y=2 C +F

(2 A +D)x+(2 B +E)y=2 C +F

And , other equation is,   D x + E y=F

Option (2),is different.Will not produce the Same Solution.

→→→→Multiply equation (2), by -3 and combining it, with the equation (1)

   Ax+By=C

  -3 D x -3 E y=-3 F

Produce the same solution, that original equation will,

→→→→Multiply equation (2), by -5 and subtracting it, from the equation,

(A-5 D) x + (B-5 E) y= C- 5 F

D x + E y=F

→→→→→Will Give the same solution, that original equation will.

Now, Coming to Option 5

A x +(B+E)y=C→ Ax + B y + E y =C→ C+E y =C→E y=0→y=0

(A+B)x+E y = C +F→A x +B x+E y=C→C - By+B x+E×0=C→B x=0→x=0

Used equation (1), to solve both the equations

Does not give, the solution set, (2, -3).

⇒≡Option , (1), (3) and (4) are system of equations with the same solution that Original equation has.

ok i honestly dont know who ben is but PREACH

if they are trying to be negitavie and report peeps they can go to the innaprotate bots and report them instead like dang im tried of people reporting others just becuase they want to or are saltly its been happening alot to me on my main acc here and i got so many warnings already so i made a back up acc just incase mine gets deleted since so many people wanna report my stuff when im not even doing anything wrong like dang!!
