Respuesta :

a)  2 / x-3 = 4
 4(x-3) = 2
4x - 12 = 2
4x = 2 + 12
x = 14/4
x = 7/2

In short, Your Final Answer would be 7/2 or 3.5

c) 7 / 2x + 5 = 2/5
7*5 = 2(2x+5)
35 = 4x + 10
4x = 35 - 10
x = 25/4

In short, Your Final Answer for this part would be 25/4

Hope this helps!

on a first add 3 to 4 you will get 7 = 2/x then you need to multiply 7 by 2.
