Question

find the value of k,if x=2,y=1 is a solution of the equation 2x+3y=k Find two more solutions of the resultant equation​

Answer 1

Answer:

if x is = 2 and y = 1

then,2×2+3×1=k

so, k=7

then two more solutions of the resultant equation is-:

if y is = -1

then,2x+3×(-1)=7

=2x-3=7

so, x=5

hence,x=5 and y=-1
