Answer:
x = 5
Step-by-step explanation:
im too tired to explain just trust me
(5) + 2 = 7
2(5) + 3 = 13
13 * 7 = 91
B*D?
B=-2
D=-6
B*D=(-2)*(-6)=12
Answer:

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)
