I hope this helped!
Step-by-step explanation:
The numbers are 9 and 10.
Let x be the first number. Since they are consecutive, this means (x+1) represents the second number.
The square of x is x². The square of (x+1) is
(x+1)²=(x+1)(x+1)=x²+1x+1x+1=x²+2x+1
The difference of these squares would be given by
x²+2x+1 - x²
Setting this equal to 19,
x²+2x+1 - x² = 19
Combining like terms,
2x+1=19
Subtract 1 from each side:
2x+1-1=19-1
2x=18
Divide both sides by 2:
2x/2 = 18/2
x = 9
The first number, x, is 9. This means the second number, x+1, is 9+1=10.

Answer:
z=3/11
Step-by-step explanation:
<h3>I hope it helps you</h3>
<h3>-2z+10+7z=16z+7</h3><h3>-2z+10+7z-16z-7=0</h3><h3>-11z=-3</h3><h3>z=3/11</h3>
<h3>*-2z+10+7z=16z+7 it is not a solution.This is called equation.</h3>
