Question

For what value of c does the following system have no solution? 1/2x+1/5y=2 5x+2y=c

Answer 1

Answer:

c(=/)20

Step-by-step explanation:

c doesn't equal 20. Put the equal sign with dash through it.

Answer 2

Answer:

Step-by-step explanation:

$\frac{1}{2}x+\frac{1}{5}y = 2 \mid 5x + 2y = c$

First let's multiply the 1st equation by 10.

$5x + 2y = 20 \mid 5x + 2y = c$

So, we can see that the equations have the same coefficients and that implies  they are equal.

So the equation has no solutions for. $c \in R \setminus{20}$
