Answer:
646 child tickets are sold
Step-by-step explanation:
Let c represent the number of child tickets sold. Then (c-186) is the number of student tickets sold, and (c+234) is the number of adult tickets sold. The total number sold is ...
(c -186) + c + (c+234) = 1986
3c +48 = 1986 . . . simplify
c + 16 = 662 . . . . divide by 3
c = 646 . . . . . . . . . subtract 16
The number of child tickets sold is 646.
To solve equations, you want to isolate the X. So, the first step will be to distribute that 4 into the 2x + 1.
4 x 2 = 8
4 x 1 = 4 So we have 4(2x+1) = 8x+4. When we plug this into the equation, that gets us 8x + 4 - 2x = -8. Next, let's combine like terms now that we've distributed everything out. 8x - 2x = 6x. Now we have
6x + 4 = -8. Next, we subtract 4 from both sides to isolate the X; 6x = -8 - 4. -8 - 4 = -12. So now we have 6x = -12. The final step to isolating the X is to divide both sides by 6; 6/6 = 1, and -12/6 = -2. Our final answer is X = -2.
We can see that 2x - 8x + x = -5x
and -6y + 11y = 5y
and 9 - 14 = -5
so simplified, it is -5x + 5y - 5
100/2 = 50
I think the answer is 50.
I hope this helps! :D
