Question 1 Report

Given that 3x - 5y - 3 = 0, 2y - 6x + 5 = 0 the value of (x, y) is
Answer Details
3x - 5y = 3, 2y - 6x = -5
-5y + 3x = 3........{i} x 2
2y - 6x = -5.........{ii} x 5
Substituting for x in equation (i)
-5y + 3( 19 24 ) = 3
-5y + 3 x  19 24  = 3
-5y =  3 − 19 8
-5 =  24 − 19 8
=  5 8
y =  5 8 × 5
y =  − 1 8
(x, y) = ( 19 24 , − 1 8 )
