Question

for value k is equal to 3 find the number of solutions of X + K Y is equal to 2 and 4 x + 4 Y is equal to 8

​

Answer 1

Answer:

X=-4.Y=2.

here the value of k is given that is 3.

so by equating both equation .we can find the X and Y

Answer 2

${\bold{\huge {\red {\mathcal {SOLUTION:}}}}}$

Given: k=3

equation are:

$x + ky = 2 \\ 4x + 4y = 8$

so the equations will be:

$4(x + 3y = 2 )\\ 4x + 4y = 8$

by elimination method:

$x = \frac{4}{11} \: and \\ y = \frac{ - 3}{4}$
