Question

Show the points (2,1),(11,2) and (20,3) are the solution of the linear equation x=9y-7

Answer 1

Answer:

hey!mate here is your answer

Step-by-step explanation:

x=2 and y=1 in first part

so,

in the general form x-9y+7=0

therefore

2-9*1+7=0

-7+7=0

0=0

hence it is a solution

then in second part

11-9*2+7=0

-7+7=0

0=0

hence it is a solution

similarly in third part

20-9*3+7=0

-7+7=0

0=0

hence it is a solution
