Answer:
10 and 4.
Step-by-step explanation:
Let x be the first number.
Let y be the second number.
x + y = 2x - 6
x - y = 4y - 10
x = 4y - 10 + y
x = 5y - 10
(5y - 10) + y = 2(5y - 10) - 6
6y - 10 = 10y - 20 - 6
6y - 10 = 10y - 26
6y - 10y = -26 + 10
-4y = -16
y = 4
x - (4) = 4(4) - 10
x - 4 = 16 - 10
x - 4 = 6
x = 6 + 4
x = 10
Solution for k/5.2+81.9=47.2 equation:
<span>k in (-oo:+oo)
k/5.2+81.9 = 47.2 // - 47.2
k/5.2-47.2+81.9 = 0
0.19230769*k-47.2+81.9 = 0 // - 81.9-47.2
0.19230769*k = -(81.9-47.2) // : 0.19230769
k = (-(81.9-47.2))/0.19230769
k = 5.20000006*(47.2-81.9)
k = 5.20000006*(47.2-81.9)
