You solve this problem by factoring. After I have factored it, the problem looks like this:

(2x - 5)(x + 1)

Then the first answer would be solved this way:

2x = 5
x = (5/2)

The second answer would be:

x = -1

Hope this helped!

balu736 [363]

Answer:

<u>The answer is the option B</u>

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
