Question

Найдите корень уравнения:
(x-1,25)*4,5=27,
(x+19,64)*0,18=144,
5,6:x-6=34,03,
x:100-1,2367=2,9633

Answer 1

1)x-1.25=27/4.5
(x-1.25)/4.5/4.5=27/4.5
x=27+5.625/4.5
x-1.25+1.25=27/4.5+1.25
x=32.6252/4.5
2)x+19.64=144/0.18
(x+19.64)*0.18/0.18=144-0.18
x=144-3.5352/0.18
x+19.64-19.64=144/0.18-19.64
x=140.4648/0.18
