Solve for x: x² - 14x + 49/x² - 49 = 3/17

x = 10

Step-by-step explanation:

Begin by factorising the numerator/ denominator of the left side

x² - 14x + 49 = (x - 7)² ← perfect square

x² - 49 = (x - 7)(x + 7) ← difference of squares

Thus left side becomes

→ x ≠ ± 7

Cancel (x - 7) on numerator/denominator, leaving

Returning to the equation, that is

= ( cross- multiply )

17(x - 7) = 3(x + 7) ← distribute both sides

17x - 119 = 3x + 21 ( subtract 3x from both sides )

14x - 119 = 21 ( add 119 to both sides )

14x = 140 ( divide both sides by 14 )

x = 10

the one that has a slope of 1/2 and is positive.
