Question

Cum pot rezolva? 35*5-54:m*4=139 ;m:2+45-25:(36-99:9)=73
Suma a doua numere este 365.Primul este cu145 maimare decat al doilea.Afla cele doua numere?

Answer 1

a + b = 365
b = a + 145
a + a + 145 = 365
2 a + 145 = 365
2a = 365 - 145
2a = 220
a = 220 : 2
a = 110
110 + b = 365
b = 365 - 110
b = 255

m : 2 + 45 - 25 : ( 36 - 99 : 9 ) = 73
m : 2 + 45 - 25 : ( 36 - 11 ) = 73
m : 2 + 45 - 25 : 25 = 73
m : 2 + 45 - 1 = 73
m : 2 = 73 - 45 + 1
m : 2 = 29
m = 29 x 2
m = 58

Answer 2

175-54:m*4=139
175-139=54:m*4
36=54:m*4
54:m=36:4
54:m=9
m=54:9=6

99:9=11
36-11=25
25:25=1
m:2+45-1=73
m:2=39
m=39*2=78
