X+ y = k
x - y = k
the solution of the system shown is
a. (0, k)
b. (0, 0)
c. (k, 0)

We are given with two equations X + y = k and x - y = k. to find the solution of the system of linear equations, we can use elimination by adding the equations to eliminate y. hence the third equation is 2x= 2k ; x = k, hence y is equal to zero. Answer is C

Hello,

I suppose X is the same as x.

x+y=k
x-y=k
2x=2k==>x=k and y=k-k=0
sol={(k,0)}

Answer C

Where is the table?
