Answer:
x=16 y=5
Step-by-step explanation:
Since triangle ABC is an equilateral all sides are equal. Since they are all equal you can do 49=3x+1 You then subtract one to the other side to get 48=3x then you divide 3 by 48 which is 16=x. For y you would do the same thing. 49=18y-41. Now you add 41 to 49 and get 90=18y. You divide 18 by 90 and get 5=y. If you want you can always check your answer by doing Taking the original problem and placing the x or y value where the variable is and is should equal to 49
