2x+1=13 x=6 so an ok answer would be: 2x+10=40 x=15
Answer: x = 23 and y = 13
Explanation:
let x and y be the two number.
Where:
(x + y)/2 = 18 => x + y = 18 x 2 = 36
and:
x - y = 10
Thus we get:
x + y = 36 (1)
x - y = 10 (2)
Add (1) and (2):
x + y + x - y = 36 + 10
2x = 46
x = 23
If x = 23
then x - y = 10
23 - y = 10
-y = -13
y = 13
Answer:
24 multi-scented candles
10 single-scented candles
Step-by-step explanation:
There was no question, so I am going to assume that you want to know how many of each type of candles were sold.
Let m = no. of multi-scented candles
s = no. of single-scented candles
(1) m + s = 34 (2) 3m + 2s = 92
s = 34 - m 3m + 2(34 - m) = 92
3m + 68 - 2m = 92
m + 68 = 92
m = 24
s = 34 - 24 = 10
