Question

1) x:5+48=56
2) 20+x=64-2
3) x.3+18:6=9
4) x:2+14:7=10
5) x.6-12=36:6
6) x+5-3=11

Answer 1

Respuesta:

Explicación paso a paso:

1) x:5+48=56

x:5 = 56 - 48

x:5 = 8

x = 8/5

2) 20+x=64-2

x = 62- 20

x = 42

3) x.3+18:6=9

3x + 3 = 9 (sacamos tercia)

x + 1 = 3

x = 3 +1

x = 4

4) x:2+14:7=10

x:2 + 2 = 10

x:2 = 10 - 2

x:2 = 8

x = 8/2

x = 4

5) x.6-12=36:6

6x - 12 = 6 (sacamos sexta)

x - 2 = 1

x = 1 + 2

x = 3

6) x+5-3=11

x = 11 +3 - 5

x = 9
