Look at deonomators
assuming that the deonomenators are 5x+15y and 2x+6y
find their LCM
factor
5x+15y=5(x+3y)
2x+6y=2(x+3y)
LCM=10(x+3y)=10x+30y
multiply 2/(5x+15y) by 2/2=4/(10x+30y)
multiply 1/(2x+6y) by 5/5=5/(10x+30y)
if we add them
9/(10x+30y)
If you need to get to nine the answer is...
6+3 or 3x1+6
Answer:(0,0) (1,-1) (8,-2)
Step-by-step explanation:I hope this helps keep pushing on to greater grades
4 prints
12x = 2.5x + 38
at 4, these expressions are equal
