A)x+x-4=17-2x+1
B)x+2x+3-5x=4x-9
C)5x+6x-16=3x+2x-4
D)5x+4=3x-2x+4

(tem que ser com operação​

Answer 1

Resposta:

a)x+x-4=17-2x+1

2x+x+x=17+1+4

4x=22

x=22/4

x=5,5

b)x+2x+3-5x=4x-9

-4x+x+2x+5x=-9-3

4x=-12

x=-12/4

x=-3

c)5x+6x-16=3x+2x-4

-2x-3x+5x+6x=-4+16

6x=12

x=12/6

x=2

d)5x+4=3x-2x+4

2x-3x+5x=4+4

4x=8

x=8/4

x=2
