X + y = 5 ; x - y =3 solve using linear combination
1 answer:
Answer:
x = 4
y = 1
Step-by-step explanation:
use one equation to solve for one variable.
y = 5 - x
Now plug the value of y in the other equation
x - (5-x) = 3
x+x= 3+5
2x=8
x=4
Now use the value of x to find the value of y on the first equation
y = 5 - x
y = 5 - 4
y = 1
