Answer:
![[3, 4]](https://tex.z-dn.net/?f=%5B3%2C%204%5D)
Step-by-step explanation:
{5x + 2y = 23
{13x + 3y = 51
−5⁄13[13x + 3y = 51]
{5x + 2y = 23
{−5x - 1 2⁄13y = 19 8⁄13 >> New Equation
______________________
11⁄13y = 3 5⁄13
_____ ______
11⁄13 11⁄13
[Plug this back into both equations above to get the x-coordinate of 3];

Step-by-step explanation:
49×12= 588
1. 50×10=500
2. 50×10+2= 502
3. 50×12-12= 588
4. 50+12-12=50
Another way to write 49×12 is 50×12-12
Answer:
15 muffins are cinnamon.
Step-by-step explanation:
Given that:
Number of muffins baked = 50 muffins
Chocolate chip muffins = 1/5 of 50 = 
Chocolate chip muffins = 10 muffins
Blueberry muffins = 1/2 of 50 = 
Blueberry muffins = 25
Cinnamon muffins = Muffins baked - chocolate chip muffins - blueberry muffins
Cinnamon muffins = 50 - 10 - 25
Cinnamon muffins = 50 - 35 = 15
Hence,
15 muffins are cinnamon.
