Question

resolva em reais
3+x=0
23x+2=2
12-7+4x=23
5x-3x=30
4x+10=23​

Answer 1

Resposta:

3 + x = 0

x = -3

23x + 2 = 2

23x = 2 - 2

23x = 0

x = 0/23

x = 0

12 - 7 + 4x = 23

4x = 23 - 5

4x = 18

x = 18/4

5x - 3x = 30

2x = 30

x = 30/2

x = 15

4x + 10 = 23

4x = 23 - 10

4x = 13

x = 13/4
