Answer 1

Answer:

x=5,y=4

Step-by-step explanation:

Let's use elimination, shall we? xD

4x+y=24

x-y=-4

step 1:  [use the distributive property]      

                    4x+y=24

                   -4(x-y=-4) -----> -4x+y=-16        (-4x cancels out)

step 2)

                   2y=24+(-16)

                   2y=8  [divide both sides by four]

                   y=4

subsitute y=4 for x -------> 4x + 4 = 24 --------> 4x=20

                                                                          divide both sides by four

x=20/4 -------------> x=5

Final answer: x=5,y=4
