Question

x + y = 6. 2x - y = 3. The system of equations. . . a.has no solution. b.has one solution. c.is coincident

Answer 1

Answer:

The answer is the option B

The system has one solution

Step-by-step explanation:

we have

$x+y=6$ ------> equation A

$2x-y=3$ ------> equation B

Adds equation A and equation B

$x+y=6\\2x-y=3\\-------\\2x+x=6+3\\3x=9\\x=3$

Find the value of y

Substitute the value of x in equation A or equation B

$3+y=6$

$y=3$

therefore

The system has one solution

Answer 2

X + y = 6 
2x - y = 3 
3x = 9 
x = 3 
y = 3 

b) One solution is right answer
