Group all the 'y' terms on the left and all the other terms on the right:
<span>2.8y+6+0.02y=5y-14 => y(2.8+0.02-5)=-14-6
Now add up 2.8, 0.02 and -5; then combine -14 and -6. Can you now solve for y?

Answer:
The second number = 30
The first number = 25
The third number = 50
Step-by-step explanation:
Let
The second number = x
The first number = x - 5
The third number = 2(x - 5)
Total = 105
105 = x + (x - 5) + 2(x - 5)
105 = x + x - 5 + 2x - 10
105 = 4x - 15
105 + 15 = 4x
120 = 4x
x = 120/4
x = 30
The second number = x
= 30
The first number = x - 5
= 30 - 5
= 25
The third number = 2(x - 5)
= 2(30 - 5)
= 2(25)
= 50
