First no. = x
Second no. = y

Equation Formation.
x = 2 y + 5
x - 2 y = 5.........equation (i)

x + y - 1 = 16
x + y = 17............. equation(ii)

Solving Equation
x + y = 17
x - 2 y = 5
     ⇅
3 y = 12
   y = 4

x = 2 y +5 
x = 2(4) + 5
 x = 13

Answer = 4 , 13

6. Santiago Diaz Granados played an arcade game that cost 25 tokens per game. In six games, Santiago won 0 tokens, 10 tokens, 50
Pavel [41]
-- To play the six games, <span>Santiago Diaz Granados spent

                                             (6 x 25) = 150 tokens.

-- As a result of his skill, experience, talent, steady hand, nerves
of steel, superior hand-eye coordination, and superb reflexes, </span><span>
Santiago Diaz Granados won</span>

                 (0 + 10 + 50 + 0 + 5 + 10) = 75 tokens.

-- At the end of the 6th game, <span>Santiago Diaz Granados was behind
the curve. 
After spending 150 tokens and winning 75 tokens, </span><span>Santiago Diaz Granados
was down by (150 - 75) = 75 tokens since he arrived at the arcade. 
Any true friend could look at the choices, could see that choice-B is
the correct one, and could advise </span><span>Santiago Diaz Granados to cash in
whatever he had left, accept his losses, return to his home, and live

Answer:

Graph 1: Consistent Dependent

Graph 2: Consistent Independent

Graph 3: Consistent Dependent

Graph 4: Inconsistent

Step-by-step explanation:

Consistent means they have at least one solution.  So lines that intersect once or lines that intersect infinitely many times are both consistent systems.

If they are the system that has one solution they are considered independent.

If they are the system that has infinitely many solutions then are considered dependent.

Inconsistent means they won't intersect at all.

First graph shows the same line graphed onto itself.  That means they have infinitely many solutions and is therefore a consistent dependent system.

Second graph shows the lines intersecting once.  That means they have one solution and therefore is a consistent independent system.

Third graph shows the same description of graph one and is therefore a consistent dependent system.

The last graph shows parallel lines. Parallel lines do not intersect and therefore do not have a solution.  So this system is inconsistent.
