2x - y = 63 so y = 2x - 63

substitute y = 2x - 63 into 3y = x
3y = x
3(2x - 63) = x
6x - 189 = x
5x = 189
x = 189/5

y = 2(189/5) - 63
y = 63/5

answer
(189/5 , 63/5)

Which are possible lengths of the sides for a triangle?

Answer:

Step-by-step explanation:

im not sure if they can be the same length, but heres the explanation: so a+b is higher than c, (9=a, 7=b, 11=c) but c is the bigger number by itself. so since a+b is higher added together, it makes it a triangle. sorry if this is wrong but i think its right.
