Answer:
x3, because when you have the powers (in x6, the "6" is the power) then you add the powers. x3 + x6 = x9. So your answer is x3.
Step-by-step explanation:
Answer:
(1/2)(10)(x + 15 + x) = (2/5)(10)(20 + x)
(1/2)(2x + 15) = (2/5)(x + 20)
5(2x + 15) = 4(x + 20)
10x + 75 = 4x + 80
6x = 5
x = 5/6
NB = 5/6
4x-10y=-20 /*(-3)
6x-15y=-30 /*2
-12x+30y=60
12x-30y=-60

0=0
