Question 1131331

(6)/(y+5)-(8)/(y-5)=(12)/(y^(2)-25) 

Solve for Y
<pre>Solve for Y <======= s/b Solve for y, as Y IS NOT the same as Y
{{{matrix(1,3, 6/(y + 5) - 8/(y - 5), "=", 12/(y^2 - 25))}}}
{{{matrix(1,3, 6/(y + 5) - 8/(y - 5), "=", 12/(y - 5)(y + 5))}}} ---- Factoring denominator on right. Note that: {{{matrix(1,3, x <> - 5, and, x <> 5)}}}
6(y - 5) - 8(y + 5) = 12 -------- Multiplying by LCD, (y + 5)(y - 5)
6y - 30 - 8y - 40 = 12
- 2y = 82
{{{highlight_green(matrix(1,5, y, "=", 82/(- 2), "=", - 41))}}}
