A)6x-17=3x+16, B)5x+100=2x-2, C)10x7=-2x-19, D)2.(x-3)=3.(2-x), E)17x-18=16x-101​

Answer 1

Resposta:

Explicação passo a passo:

A)6x-17=3x+16

6x-3x=16+17

3x=33

x=33/3

x=11

B)5x+100=2x-2

5x-2x=-100-2

3x=-102

x=-102/3

x=-34

C)10x-7=-2x-19

10x+2x=7-19

12x=-12

x=-12/12

x-1

D)2(x-3)=3(2-x)

2x-6=6-3x

2x+3x=6+6

5x=12

x=12/5

x=2,4

E)17x-18=16x-101

17x-16x=-101+18

x=-83
