Question

URGENTEEE!!!!!

5x – 3x = 30 - (-2x + 1)

23x + 2 = 2 . (3x + 5) - 6
​

Answer 1

Explicação passo-a-passo:

a) 3+x=0

x = - 3

b)23x+2=2

23x = 2 - 2

23x = 0

x = 0/23

x = 0

c)12-7+4x=25

4x = 25 - 12 + 7

4x = 20

x = 20/4

x = 5

d)5x-3x=30

2x = 30

x = 30/2

x = 15

e)4x+10=45-3x

4x + 3x = 45 - 10

7x = 35

x = 35/7

x = 5
