Question

For what value of c, the linear
equation 2x+cy= 8 has equal
values of x and y for its
solution?
​

Answer 1

Answer:

value of 'c' is 2

Step-by-step explanation:

2x - cy = 8 and x =y

so, 2x - cx = 8

x (2 - c) = 8

x = 8 / (2-c)

denominator should not be zero

so, 2 - c = 0

c = 2

except value of c=2 the solution can be founded.

Answer 2

Answer:

hi I hope this answer will help u

Step-by-step explanation:

According to the problem given,

2x+cy=8.....(1)

and X=y.....(2)

put y=X in equation (1) we get,

2x+CX=8

take X common

X(2+c)=8

X=8/(2+c)

but denominator should not be zero

2+c is not equals to zero

c is not equals to -2

and c=0,2and 6 satisfies the condition

2x+Ch=8

has Equal values of X and y.
