1. 
; 3
Let's solve for a.
(subtraction property of equality)
(division property of equality)
Therefore, 3 is a solution to 9 = 2a + 3
2. 
; 7
(- × - = +)
(Subtraction property of equality)
(division property of equality)
Therefore, 7 is not a solution of
3. 
; 1
Therefore, 1 is a solution of .
As far as the old dimensions of the photo are concerned,
Width of the photo = 3"
Length of the photo = 5"
New length of the photo = 7 inches
Let us assume the new width of the photo = x inches
Then
3/5 = x/7
5x = 7 * 3
5x = 21
x = 21/5
= 4.20 inches
So the correct option among all the options that are given in the question is the first option. I hope that the answer has come to your help.
