Answer:

Option B is correct

No solution

Explanation:

Given the system of equation:


3y+3x=2 ......[1]


y+x= 8 ......[2]

We can write equation [2] as

y =8-x

Substitute this in [1] we have;


3(8-x)+3x =2

Using distributive property:
a\cdot (b+c) = a\cdot b+ a\cdot c


24-3x+3x = 2

Combine like terms;


24 = 2 false.

⇒ the system of equations does not have any solution.

Using Graphing calculator:

You can see the the graph of the system of equations as shown below:

The graph of the lines do not intersect, so the graphs are parallel and there is no solution.
