Question

(6x9-b)-3x10+16:2=4x3x1
Și
[(26-m)x9:3]+108x7=900-84

Answer 1

( 6 × 9 - b ) - 3 × 10 + 16 : 2 = 4 × 3 × 1

( 54 - b ) - 30 + 8 = 12 × 1

( 54 - b ) - 30 + 8 = 12

( 54 - b ) - 30 = 12 - 8

( 54 - b ) - 30 = 4

54 - b = 4 + 30

54 - b = 34

b = 54 - 34

b = 20

[ ( 26 - m ) × 9 : 3 ] + 108 × 7 = 900 - 84

[ ( 26 - m ) × 9 : 3 ] + 756 = 816

( 26 - m ) × 9 : 3 = 816 - 756

( 26 - m ) × 9 : 3 = 60

( 26 - m ) × 9 = 60 × 3

( 26 - m ) × 9 = 180

26 - m = 180 : 9

26 - m = 20

m = 26 - 20

m = 6

Answer 2

(6×9 - b) - 3 × 10 + 16 : 2= 4 × 3 × 1

(54 -b) - 30 + 8 = 12

54 - b = 12 + 30 - 8

54 - b = 34

b = 54 - 34

b = 20

[(26 - m) × 9 : 3] + 108 × 7 = 900 - 84

[(26 - m) × 3] + 756 = 816

(26 - m) × 3 = 816 - 756

(26 - m) × 3 = 60

26 - m = 60 : 3

26 - m = 20

m = 26 - 20

m = 6
