Answer 1

47,17-5,8y=11,326 => -5,8y=11,326-47,17 => -5,8y=-35,844 =>y=-35,844/-5,8 => y=6,18

65:t-1,7=14,55 =>65/t=14,55+1,7 => 65/t=16,25 => 16,25t=65 => t=65/16,25 =>t=4

k:25+19,91=20,302 =>k/25=20,302-19,91=> k/25=0,392=> k=0,392·25 =>k=9,8

46,01-8,9:j=42,45 => -8,9/j=42,45-46,01 => -8,9/j=-3,56 => -3,56j=-8,9 => j=-8,9/-3,56 => j=2,5

(6,1r-35,24):2+5,7=6,685 => 12,2r-70,48+5,7=6,685 => 12,2r=6,685-64,78 =>
12,2r=-58,095 => r=-58,095/12,2 => r=-4,76

96-(96-96:d)•0,75=33,6 => 96-72+72/d=33,6 => 72/d=33,6-24 => 72/d=9,5 => 9,5d=72 =>d=7,57

18,5x+4,6=24,3x-49,92 => 18,5x-24,3x=-49,92-4,6 => -5,8x=-54,52 =>x=9,4

45,3-3,2z=7,1z+27,79 => -3,2z-7,1z=27,79-45,3 => -10,3z=-17,51 => x=1,7
