10%...3*15*x+2*18*(0,22-x)=9...solve for x

Thanks for the changes. Here is my answer.

3 Fox jeans before discount - 45$
2 pony jeans before discount - 36$

Let x be the discount for FJ and y be the discount for PJ.

45 * (X/100) + (36 * Y/100) = 9
X + Y = 22
.45 X + (.36 (22 - X)) = 9
.45 X + 7.92 - .36X = 9
.09 X = 1.08
X = 12 and Y = 10
Hence Discount for PJ = 10%

Discount on pony is 10 %

x+y =22

3*15*x/100+2*18*y/100=9

solve for y ...10%
