Question

22-5x(38-4xg) = 12
26+(6×h-7×3)÷9=27
​

Answer 1

Răspuns:

22 - 5 × ( 38 - 4 × g ) = 12

22 - 12 = 5 × ( 38 - 4 × g )

10 = 5 × ( 38 - 4 × g )

10 : 5 = 38 - 4 × g

2 = 38 - 4 × g

4 × g = 38 - 2

4 × g = 36

g = 36 : 4

g = 9

26 + ( 6 × h - 7 × 3 ) : 9 = 27

( 6 × h - 7 × 3 ) : 9 = 27 - 26

( 6 × h - 7 × 3 ) : 9 = 1

6 × h - 7 × 3 = 1 × 9

6 × h - 7 × 3 = 9

6 × h - 21 = 9

6 × h = 9 + 21

6 × h = 30

h = 30 : 6

h = 5
