Problem 1
Given;
(1) 1/a + 1/b = 8
Write the equation for b. Rewrite (1) to get
(2) 1/b = 8 - 1/a or
(3) 1/b = (8a -1)/a, now "flip" both sides of (3) to get
(4) b/1 = a/(8a-1) or
(5) b = a/(8a-1)
Problem 2
Given;
(6) M+=+sqrt%284st%29
Square both sides of (6) to get
(7) M%5E2+=+4st, now divide both sides of (7) by 4s to get
(8) M%5E2%2F%284s%29+=+t or
(9) t+=+M%5E2%2F%284s%29
