Question 12 (4 points) Solve the System of Equations 2x - 5y = 13 3x + 4y = –15 O (-1,-3) 0 (-3,1) (3,1) (1,3) Question 13 (4 points) Solve the System of Equations 7x + 9y = -34 - 4x - 64 = 20

Answer 1

D 2x-5y=13 — 0 - 30 + 4y=-15 - Multiply excis by and eqci, by s 8x-2o4=52 15k & Roy =-75 23x --23 x=235=-17 Put the naken of in egr cij 23-59=13 =) 2X(+1)+s4=!3 - 2*54=13=)-54=1372 =-sy=15 => y = 18 =)-y=3 => '08-31 : Solution of these equation is (x,y)= (-133) option() is correct
