x + y = 9
y = 4 ?x ?
What is the solution of the? system?
Select the correct choice below? and, if? necessary, fill in the answer box to complete your choice.
A. There is one solution. The solution of the system is nothing . ?(Simplify your answer. Type an ordered? pair.)
B. There are infinitely many solutions of the form left parenthesis x comma nothing right parenthesis x, . ?(Simplify your? answer.)
C. There is no solution. Click to select and enter your answer(s).
Explanation / Answer
From equation 2
y=4-x gives x +y=4 So from equation 1 gives x+y=9
For no values of x and y the equation x +y cannot be equal to 4 and 9 at same time
So correct answer is C
There is no solution
