Answer:
Step-by-step explanation:
let x be the numerator of the rational number then 2x is the denominator
original fraction =
subtracting 3 from numerator and adding 7 to denominator , gives
= ( cross- multiply )
5(x - 3) = 2(2x + 7) ← distribute parenthesis on both sides )
5x - 15 = 4x + 14 ( subtract 4x from both sides )
x - 15 = 14 ( add 15 to both sides )
x = 29
rational number =

Answer:
1/8
Step-by-step explanation:
To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that
X + 14 - 14 = 56 - 14
X=42
Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.
