Step-by-step explanation:
9X+5Y=35
2X+5Y=0
-(2X+5Y=0)
-2X-5Y=0
9X+5Y=35
7X=35
X=5
2(5)+5Y=0
10+5Y=0
5Y=-10
Y=-2
X=5 Y=-2
One way to do this is to factor both parts of the fraction (prime factors):-
45 = 3*3*5
243 = 3*3*3*3*3
note that 3*3 is common to both factors
so we can write its as 5 / 3*3*3 = 5/27
