Step-by-step explanation:
Question 1 Solve the following pairs of equations by reducing them to a pair of linear equations:
(i) 1/2x + 1/3y = 2 (ii) 2/x^0.5 + 3/y^0.5 = 2
1/3x + 1/2y = 13/6 4/x^0.5 - 9/y^0.5 = -1
(iii) 4/x + 3y = 14 (iv) 5/(x-1) + 1/(y-2) = 2
3/x - 4y = 23 6/(x-1) - 3/(y-2) = 1
(v) (7x-2y) / xy = 5 (vi) 6x+3y=6xy
(8x+7y) / xy = 15 2x+4y=5xy
(vii) 10/(x+y) + 2/(x-y) = 4 (viii) 1/(3x+y) + 1/(3x-y) = 3/4
15/(x+y) - 5/(x-y) = -2 1/[2(3x+y)] - 1/[2(3x-y)] = -1/8
