(1) 3x-7=-16

(2) 13x + 2=5 x +18.

(3) 5÷(x-2)=3÷(x+2)

(4) (x-1)÷2=-1+15​

Answer 1

Respuesta:

(1) x = -3

(2) x = 2

(3) x = -8

(4) x = 29

Explicación paso a paso:

(1) 3x - 7 = -16

3x = -16+7

x = -9/3

x = -3

(2) 13x + 2 = 5x + 18

13x - 5x = 18 - 2

8x = 16

x = 16/8

x = 2

(3) 5/(x - 2)=3/(x + 2)

5(x + 2) = 3(x - 2)

5x + 10 = 3x -6

5x - 3x = -6 -10

2x = -16

x = -16/2

x = -8

(4) (x - 1)/2 = -1 + 15​

x - 1 = 14(2)

x - 1 = 28

x = 29
