(3+x)/3+ (2-x)/5= 3-2x
(3+x)/3+ (2-x)/5= 3-2x
trzeba pomnozyc razy 15 5(3+x)+3(2-x)=15(3-2x) 15+5x+6-3x=45-30x 2x+21=45-30x 2x+30x=45-21 32x=24 x=24/32 x=3/4
(3+x)/3+ (2-x)/5= 3-2x / *15 5(3+x)+3(2-x)=15(3-2x) 15+5x+6-3x=45-30x 32x = 24 / :38 x = 24/32 x = 3/4
(3+x) /3 + (2-x) /5 = 3-2x / *15 5(3+x) + 3(2-x) = 15(3-2x) 15 + 5x + 6 - 3x = 45 - 30x 32x = 24 /:38 x = 24 /32 x = 3/4
