Question

află necunoscutul:(5×5+6×6-r)+6×5-5×16=9÷3​

Answer 1

( 5 × 5 + 6 × 6 - r ) + 6 × 5 - 5 × 16 = 9 : 3

( 25 + 36 - r ) + 30 - 80 = 3

( 61 - r ) + 30 - 80 = 3

( 61 - r ) + 30 = 3 + 80

( 61 - r ) + 30 = 83

61 - r = 83 - 30

61 - r = 53

r = 61 - 53

r = 8

Answer 2

(5×5+6×6-r)+6×5-5×16=9÷3
(25+36-r)+6×5-5×16=3
(61-r)+30-80=3
(61-r)+30=80+3
(61-r)+30=83
(61-r)=83-30
(61-r)=53
r=61-53
r=8
