18+63y=n(2+7y)n

Solution

18 + 63 y = n (2 + 7 y) n

Solution

y = - \frac{2}{7}; n \neq = 3, n \neq = - 3

+1

Decimal Notation

y = - 0.28571 \dots

Solution steps

18 + 63 y = n (2 + 7 y) n

Expand

n (2 + 7 y) n : 2 n^{2} + 7 n^{2} y

18 + 63 y = 2 n^{2} + 7 n^{2} y

Move

18

to the right side

63 y = 2 n^{2} + 7 n^{2} y - 18

Move

7 n^{2} y

to the left side

63 y - 7 n^{2} y = 2 n^{2} - 18

Factor

63 y - 7 n^{2} y : 7 y (9 - n^{2})

7 y (9 - n^{2}) = 2 n^{2} - 18

Divide both sides by

7 (9 - n^{2}); n \neq = 3, n \neq = - 3

y = - \frac{2}{7}; n \neq = 3, n \neq = - 3
