c) 40-5+4x-2x=20
d) 18+4x4x-3=38​

Answer 1

Explicação passo-a-passo:

a) 3x+5-3=-2x+4-20-8

3x+2=-2x-24

3x+2x= -24-2

6x=-26

x= -26/6

b)14+5-6x=8-3+2x

19-6x=5+2x

-6x-3x=5-19

-9x=-14

x= 14/9

c) 40-5+4x-2x=20

2x= 20-35

2x=15

x=15/2

d) 18+4x4x-3=38

16x+15 =38

16x=38-15

16x=23

x=23/16
