What is the value of x Data 1 x - 2y 7 Data 2 4x 28 8y

since x,y and the constt are proportional thus there is no unique value of x and y .infinite solutions.
10 years agoHelpfull: Yes(4) No(1)
both are same equations
x-2y=7
4(x-2y)=28 or x-2y=7

No solution exists

x=1 satisfies both equation
10 years agoHelpfull: Yes(2) No(9)
this system represent same line hence infinitely many solution.
10 years agoHelpfull: Yes(2) No(1)
as both the line are parallel to each other hence an infinite solution exits for x ans y

x=1
y=-3
if we assume x=1,den from 1st eqn y=-3
and if we put these values to the eqn 2,den it satisfies

both euatios are same if we multiply 1 with 4 so the both are cancle and no optiopn of this question is provided
10 years agoHelpfull: Yes(0) No(1)
the ans is x=0
10 years agoHelpfull: Yes(0) No(2)
as both equation given are straight lines and are coincident on eacg other so x has infinitely many solutions.
10 years agoHelpfull: Yes(0) No(2)
this is a data sufficiency method, so both 1&2 are not sufficient to answer this question.
10 years agoHelpfull: Yes(0) No(0)
solution can't be determined bcoz on solving the equation everything gets cancelled out.

X=9 and Y=1

What is the value of x?
Data 1: x - 2y = 7
Data 2: 4x – 28 = 8y
