Question

(9x over 7)-x=x-28 over 21
solve the equation

Answer 1

\[(\frac{ 9x }{ 7 }) - x = (\frac{ x-28 }{ 21 })\]
First, find the least common denominator, which is 21.
Then multiply that through for each term:\[(21)(\frac{ 9x }{ 7 }) - (21)x = (21) (\frac{ x-28 }{ 21 })\]

27x - 21x = x - 28
6x = x - 28
5x = -28
x = -28/5
