Question

Vreau si eu un raspuns a×7+9×6=103 si a:4+90:10=17

Answer 1

A *7+9*6=103/a*7=c

c+9*6=103

c=103-54

c=49

a*7=49

a=49:7

a=7

a:4+90:10=17/a:4=c

c+90:10=17

c+9=17

c=17-9

c=8

a:4=8

a=4*8

a =32

Answer 2

Răspuns:

a x 7 + 9 x 6= 103 ;a x 7 + 54 = 103 ;a x 7 = 103-54;a x 7 = 49; a= 49:7; a=7

a: 4 + 9= 17 ; a:4 =17-9; a:4= 8; a = 8 x 4; a= 32
