Question

porfavor es examen le doy coronita al que me responda rapido ​

Answer 1

Respuesta:

e) = 3 (2x+5) / 3 = 15

= 2x + 5 = 15

= 2x = 15-5

=2x = 10

entonces x = 10/2 ; x = 5

f) = 8 (x -2)/5= 8

=8(x-2)= 8×5

=8(x-2)=40

= x-2= 40/8

x-2= 5

x= 5+2

x= 7

g). = 2x+10= x +30

2x +10 - x = 30

x = 30-10

x = 20

h) = 10x +20=6x +8

10x =6x +28

19x-6x=28

4x= 28

x= 28/4

x= 7
