Answer:
The numbers are 8 and 6
Step-by-step explanation:
Let x and y be the two numbers
x+y = 14
x-y = 2
Add the two equations together
x+y = 14
x-y = 2
--------------
2x +0y = 16
Divide by 2
2x/2 = 16/2
x = 8
Now find y
x+y = 14
8+y =14
Subtract 8 from each side
8+y-8 =14-8
y =6
The numbers are 8 and 6
Answer:

Answer: In first question answer is -28x+4
In second question required inequality is 3x+100 < 2x-250
Step-by-step explanation:
1. Since, here the given expression is 4(x+5)-8(2+4x)
= 4x+20-16-32x ( By distributive property)
=-28x +4 ( By operating like terms)
2. Here, let the number is x.
Then according to the given question, three times the number of candy is increased by 100
That is, 3x+100
And, 250 less than the two times of the candy
That is, 2x-250
And, 3x+100>2x-250
Which is the required expression.
Hence she should subtract 250 from 2x not 2x from 250.
