7 + x/4 = 5 (common denominator is 4)
4(7+x/4) = 4 x 5 (distribute the 4 though parenthesis)
4 *7 +4x/4 = 4 x 5
4 * 7 + x = 4 x 5
28 + x = 4 x 5
28 + x = 20 (subtract the 28)
x = 20 - 28
x = -8
Answer:

Answer:
it could be any number less then 9 so examples would be 8,7,6,5,4,3,2,1 so on so forth
Simplify answer is 6x + 21
