Answer:
1) 12/18
2) 15/25
3) 32/40
4) 6/14
5) 8/15
6) 16/24
7. 12/27
Step-by-step explanation:
The equation is balanced by the 3's on both sides so that cancels out. we are left with:
x^2-6x=0
we take out an x, leaving us with:
x(x-6)=0
we know that to find the solution [ or "zero's", ] we must set "x"=0, and "x-6"=0.
the solutions are: x=0 and 6.
