Respuesta :
x + y = 6
2x - y = 3
3x = 9
x = 3
y = 3
b) One solution is right answer
2x - y = 3
3x = 9
x = 3
y = 3
b) One solution is right answer
Answer:
The answer is the option B
The system has one solution
Step-by-step explanation:
we have
[tex]x+y=6[/tex] ------> equation A
[tex]2x-y=3[/tex] ------> equation B
Adds equation A and equation B
[tex]x+y=6\\2x-y=3\\-------\\2x+x=6+3\\3x=9\\x=3[/tex]
Find the value of y
Substitute the value of x in equation A or equation B
[tex]3+y=6[/tex]
[tex]y=3[/tex]
therefore
The system has one solution
