Question

Show that (2, 1) is a solution of the system of equations.

Answer 1

Answer:

x = 2

y = 1

Step-by-step explanation:

y = -x + 3

x + 3y = 5

x + 3(-x + 3) = 5

x - 3x + 9 = 5

-2x + 9 = 5

-2x = 5 - 9

-2x = -4

x = -4/-2

x = 2

y = –x + 3

y = -2 + 3

y = 1

Answer 2

X+3y=5
Y=-x+3
X=2
Y=1
