Question

If linear equation 2x + cy=8 has equal
values of x and y, then find the value of c
when value of x=1​

Answer 1

Answer:

6

Step-by-step explanation:

value of x=y

X=1

y=1

putting value of x and y in the given equation

2*1+c*1=8

2+c=8

c=6

Since values of x and y are equal

Therefore, x = y = 1.

Now put x = 1 and y = 1 in 2x + cy = 8, so we get

2×1 + c×1 = 8

c = 8 - 2

c = 6
