number 8 is the product o hope i got it in time for you
A3=2.6
a4=?
a5=-.4

Answer:
-20
Step-by-step explanation:
Let the number be Y
If the sum of a number and seven is doubled, the result is six less than the number, The statement is as expressed below
2(Y+7)= Y-6
Find the value of Y
2Y+14=Y-6
Put the like terms together
2Y-Y=-6-14
Y=-20
The number is therefore -20
<em>Verifying</em>
2(-20+7)=-20-6
2(-13)=-26
<u>-26=-26</u>
