I dont understand help

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

answer: 15

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
