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:

Ans. Value of c is 2

Step-by-step explanation:

2x+2y=8

2(x+y)=8

x+y=4

now,

• put the value of of x is 2 then the value of y .
• In this case x and y is equal.

Answer 2

2x+cy=8,so first x=1,c=2 or it can also be 3 and y=3 or 2,So, 2*1 + 2*3=8. 2+6=8
