Question

решите уравнения
1)15,62+x=20
2)9,54-x=7,268
3)x-36,76=19,24
4)x+0,24=8,1

Answer 1

$1);;15,62 + x = 20 \\x = 20,00 - 15,62\\x = 4,38\\\2) ;;9,54 - x = 7,268\\x = 9,540 - 7,268\\x = 2, 272\\\3);; x - 36,76 = 19,24\\x = 36,76 + 19,24\\x = 56\\\4);;x + 0,24 = 8,1\\x = 8,10 - 0,24\\x = 7, 86$
