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
