Answer: 3rd answer choice; A and C
Step 1 is to locate the point (1,2). You start at the origin, then move 1 unit to the right and 2 units up. Alternatively, you can draw a vertical line through 1 on the x axis and a horizontal line through 2 on the y axis. The horizontal and vertical line cross at (1,2)
Step 2 is to then determine which lines go through (1,2). The two lines in question are line A and line C. So the intersection of line A and line C is the point (1,2). This point satisfies the equations that make up these lines. So that is why it is considered a solution to just these two equations only (ignore the other lines).
Answer:
6
Step-by-step explanation:
3 + 3 = 6
5x + 3y = 7> (4) 5x + (4) 3y = (4) 7
4x + 5y = 3> (-5) 4x + (-5) 5y = (-5) 3
20y + 12y = 28
-20x -25y = -15
(X's cross out) 12y - 25y = 28 -15
-13y = 13
Y = -1
(Plug in for y) 5x + 3(-1) = 7
5x -3 =7 (add 3 to 7)
5x = 10 (divide by 5)
X= 2
Ordered Pair= (2, -1)
