Question

Solve x and y. 17x+9y=31, 9x+11y = 29

Answer 1

Answer:

x = 40/53

Step-by-step explanation:

17x  +  9y  =  31    ---------------- (1)

9x  +  11y  =  29   ---------------- (2)

(1) * 11 => 187x  + 99y  =  341

(2) * 9 =>  81x  + 99y  =  261

            (-)                                

               106x            = 80

=> x = 80/106

=> x = 40/53
