Since all sides are equal, it is an equilateral triangle. Therefore each angle equals 60°.
7x - 3 = 60
7x = 63
x = 9
Answer: third one
Step-by-step explanation:
You want the minimum of the solutions to
x + y = 24
7x - y = 16
There are many ways to solve these equations. Adding them together, you get
8x = 40
x = 5
Since this value is less than 12, it is the smaller number. The smaller number is 5.
