ayuda con esto porfa y no poner que no se @si-ah-bueno.​

Answer 1

Respuesta:

A) 2x + 3 = x + 70

2x - x = 70 - 3

x = 67

B) 3(x + 5) = x + 4

3x + 15 = x + 4

3x - x = 4 - 15

2x = - 11

x = - 11/2

C) x/2 + 3x/4 = 15

4x + 6x/8 = 15

10x = 15.8

10x = 120

x = 120/10

x = 12

D) 8x + 3 = 21

8x = 21 - 3

x = 18/8

x = 2,25

E) 6x - 41 = 2x + 6

6x - 2x = 6 + 41

4x = 47

x = 47/4

x = 11,75
