Solve the following systemof equations
x + 3y = 9
x = 4 - 3y
I didn't mention...
Is the solution an ordered pair or is there no solution
(4-3y) + 3y = 9
solve for y!
then plug the y value into
solve for x!
you tell me. does y= a number? then, yes, it's an ordered pair
-3y and postive 3y cancel each other out, leaving 4 = 9, which is false.
So that means that there is not solution?
