So, looking at the options, only Option A has the same result as given question
So,
Option A is correct.
Answer: It is 2.
Step-by-step explanation:
Make both equation equal to each other and solve for x, as following:
- Add like terms.
- Factor the equation.
Substitute the value of x obtained into any of the original equations to obtain the y-coordinate.
Then, this is:
Line A: 2x+2y=8 ⇒2y=-2x+8 ⇒ y=-x+4
Line B: x+y=3 ⇒y=-x+3
Therefore: y=y then:
-x+4=-x+3
-x+x=3-4
0≠-1 ⇒There is no solution because the lines are parallels
Answer: There is no solution
Answer:
D ; 0
