C)5x-3+x=2x+9
D)17x-7x=x+18

(tem que ser com operação​

Answer 1

A- 16x-1=12x+3
16x - 12x = 3 + 1
4x= 4
x= 4/4
x= 1

B- 3x-2=4x+9
3x- 4x=9+2
-x= 11 (-1)
x= -11

C- 5x-3+x= 2x + 9
Stars

Answer 2

Resposta:

A)16x-1=12x+3

16x-12x=3+1

4x=4

x=4:4

x=1

B)3x-2=4x+9

3x-4x=9+2

-1x=11 .(-1)

1x=-11

x=-11:1

x=-11

C)5x-3+x=2x+9

5x+x-2x= 9+3

6x-2x=12

4x=12

x=12:4

x=3

D)17x-7x=x+18

17x-7x-x=18

10x-x=18

9x=18

x=18:9

x=2
