Ответ:
First we'll add up all our costs, and then set the equation equal to 76, because the total was $76.
x (candy) + 35 (tickets) + 25 (popcorn) + 10 (drinks) = 76 (total)
Now let's simplify this, by adding together our known prices.
35 + 25 + 10 = 70.
So now we've got the equation x + 70 = 76.
Now we just solve for x in this simple one-step equation.
x + 70 = 76
All you do is subtract 70 from both sides to get rid of the '+ 70'
x + 70 = 76
- 70 -70
x = 6.
And that's our solution. This means that the oldest son spent $6 on candy.
We can check this by substituting our solution back into our equation.
We do this by replacing any variable x with our solution, 6.
x + 70 = 76
(6) + 70 = 76
76 = 76
Seem right? Yep!
The oldest son spent $6 on candy, final answer.
Hope this helps!!
