Alright so, After rewriting the equation in a standard parabola, you get: 4 x 2 (y-0) =(x - 0)^2
Simplify it to get: y= 0-p y= 0-2
When you simplify that, your answer is: y=-2
There you go folks, just saved you from reading that long paragraph of an answer the other guy has (I don't even think the answer is in there lol, I think he just wanted to help people solve it but still most people come here for answers)
One simple way to approach this is to subtract the number that DOESN’T have the variable with the solution by the sum. Lets use problem 1 as the example: 1.) N+8=13 In this case, we subtract 13 by 8 and get 5, therefore N= 5.
2.) B+17=62 62-17= 45 B= 45
3.) X+5/6= 7/16 7/16-5/6= -19/48 X= -19/48
4.) y+1/7=5/8 5/8-1/7= 27/56 Y= 27/56
5.) 14+y=69 69-14=55 Y=55
6.) c+3.6=4.9 4.9-3.6=1.3 C= 1.3
Now for the word problems: Lets use 7 as the example- 7.) a number increased by 19 is equal to 221. Since we don’t know the number being increased by 19, that will be our variable. It will be re-written as so:
N + 19 = 221
Where N is the unknown number.
Using the same method of subtracting by the sum and the number that’s not the variable, we’ll get the solution to N 221-19= 202 N= 202
