Question

X+y=5 2x - y = 1 Need help

Answer 1

Answer:

y = 3

x = 2

Step-by-step explanation:

x+y=5  ==   -2x - 2y = -10

2x-y = 1 ==  2x - y = 1    +

                  -------------------

                  -3y = -9

                  y = 3

x + y = 5

x + 3 = 5

x = 2

Answer 2

(2,3)



Step-by-Step:


(1) x+y=5
2x-y=1


(2) add column by column (positive y plus negative y cancels out, equaling 0)

3x=6


(3) divide both sides be 3

x=2


(4) sub 2 in for x for either equation ( i chose the top one)

2+y=5


(5) subtract 2 from both sides

y=3


(6) put your answer in ordered pairs
