Respuesta :
34 + 2x = 49
minus 34 from both sides
2x = 15
divide both sides by 2
x = 7.5
(to confirm 2x = 15, 34 + 15 = 49)
Answer:
x = 7.5
Step-by-step explanation:
Use algebraic manipulation (and remember that anything you do to one side must be done to the other, in most cases):
34 + 2x = 49
-34 -34
2x = 49 - 34
2x = 15
x = 7.5
