5x - 5 + 3 = 7x + 7
Simplify 5x - 5 + 3 to 5x - 2
5x - 2 = 7x + 7
Subtract 5x from both sides
-2 = 7x + 7 - 5x
Simplify 7x + 7 - 5x to 2x + 7
-2 = 2x + 7
Subtract 7 from both sides
-2 - 7 = 2x
Simplify -2 - 7 to -9
-9 = 2x
Divide both sides by 2
-9/2 = x
Switch sides
<u>x = -9/2</u>

Answer:
15 feets, 11.25 inches
Step-by-step explanation:
Given that:
Scale = 1 : 48
Thus means that the model is 1/48 the actual size of the jet
Length of fighter jet = 63feets, 9 inches
Converting the entire length to inches
1 feet = 12 inches
63 feets = (12 * 63) = 756
Lenght of jet = (756 + 9) = 765 inches
1/48 * 765 = 15.9375 ; 15 feets, 11.25 inches
Hence, length of model = 15 feets, 11.25 inches
