Question

aflați × a:512-x=134 x:6=178 (5×5+4):6-1=3

Answer 1

512 - x = 134

x = 512 - 134

x = 378 → scazatorul

V:   512 - 378 = 134

_________________

x : 6 = 178

x = 178 × 6

x = 1 068

V:  1 068 : 6 = 178

________________

( 5 × X + 4 ) : 6 - 1 = 3

( 5 × X + 4 ) : 6 = 3 + 1

( 5 × X + 4 ) : 6 = 4

5 × X + 4 = 4 × 6

5 × X = 24 - 4

5 × X = 20

X = 20 : 5

X = 4
