Question

his is the graph for the system of equation y=1/3x+3 and x+y=7. What is the solution of this system?



3,4


-3,-4


-3,4


3,-4

Answer 1

y=1/3x+3----(1)
x+y=7-----(2)

in equation (2)
x+y=7
x=7-y

put value in equation (1)

y=1/3x+3
y=1/3(7-y)+3
y=7/3-y/3+3
y+y/3=7/3+3
4y/3=16/3
4y=16
y=4

put value in equation (2)
x+y=7
x+4=7
x=7-4
x=3

(x,y)=(3,4)

Answer 2
