please help me :)
Given the following system of equations
x + y = 4k
2x = k
where k is a constant Real Number, solve the system for (x, y) in terms of k. Do not replace
the constant k with a numerical value. Give your solution as an ordered pair.

Best ResponseYou've already chosen the best response.2You can solve it by substitution the 2x=k gives you x=k/2 replace the x in the first equation with k/2 and then solve for y

Best ResponseYou've already chosen the best response.2do you see the x=k/2 ? This means x is k/2. Do you see the x in the first equation, the equation that is x+y=4k? This means you can place that x in that equation with k/2 .

Best ResponseYou've already chosen the best response.0i see that yeah and when you plug it, k/2+y=4y

Best ResponseYou've already chosen the best response.2you are just to replace x with k/2 and then solve for y
