2x + y = 3
3x - y = 12
Add both equations
5x = 15, x = 3
2(3) + y = 3
6 + y = 3, y = -3
Solution: x = 3, y = -3... or (3,-3)
Answer:
Step-by-step explanation:
it is correct.
solution is intersection of two lines.
it is x=-0.5 and y=1.5
or (0.5,1.5)
provided each square represents 1 unit.
Identify the numbers closest to the center between whatever letters you're given, if you're given a number near the center, determine the two letter it it between along the egde of the circle. That's all it is.
Let the number of free throws be x and that of point shots be y
x+y=25
⇒x=25-y...i
also:
x+2y=46...ii
substituting i in ii we get:
(25-y)+2y=46
solving for y we get:
y=21
hence
x=25-21=4
thus the number of free shots was 4 and that of point shots was 21
