Lets take this equation step by step. (set up the equation)
12 + 0.35x = 20.05 (first we should subtract 12 from both sides.)
- 12 = -12 (Now the 12 on left side cancels out. And we solve the right)
0.35x = 8.05 (now divide both sides by 0.53 to isolate the x)
÷0.35 = ÷0.35 ( Now the left side cancels out. And we solve the right.)
x = 23 (we have found our answer!)
So your answer is D. 23
Good Luck! :)
