x+ y = 5 2x-y = 4 solve x and y

x+ y = 5   


2x - y =


First multiply everything in the first equation by 2
.


By multiplying everything in the first equation by 2 ,
you should get :


2x + 2y =
10


2x - y = 4 now subtract the two equation
.


By subtracting the two equations , you should get
:


3y = 6 divide both sides by 3
.


By dividing both sides by 3 , you should get
:


y = 2 which is your answer for " y


Now plug " y " into one of the
equation 


x + 2 = 5 subtract both sides by 2
.


By subtracting both sides by 2 , you should
get


x = 3 which is your answer for " x


So " x " equals to 3 and " y " equals to
2
