Question

Solve the system of equations by letting A = 1/x and B = 1/y. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, set y = t. and solve for x in terms of t.) 6.6 = 5 2 + 3 = 0 (x, y) = Need Help? Read It Watch It Talk to a Tutor

Answer 1

let A /X & B=/y. we have + Der Let žģ-0 a=6 , b = -6 a & bi a2 br & gives Q2=2 9 bz=3 a unique solution. - Now Take A = 1/2 & B =/ : 6( 12 ) 6 ( ) = 5 = 6A 6B = 5 - 247) +344) -0 24 +38 = 0 Polving, we get Then, 6A - 6B = 5 ZA + 38 = 0 6/A - EB -5 6A + 9B=0 -15B=5 Then & & = -5/15 - - 13. GA - 66 = 5 – - GA+2 = 5 - A-3/6 = 1/2 6A-61-1/3) = 5 de & A = 1 / 2 = x=2 B - - 1 3 - y = -3 (x,y) = ([2,-3) Aug Hence
