How is "y more than 4 is -36" written and what is the answer ​
Crazy boy [7]

Answer:

y+4=-36 and the answer is y=-40

Step-by-step explanation:

So the word is means equals, meaning we can change it to say

"y more than 4 = -36

and more than means addition so we can put a plus sign there and we get

y+4=-36

then to solve this equation we need to get y by itself on one side and to do that we can move the 4 to the other side by subtracting it on both sides to cancel out the addition and we get y=-40

I hope this helps and please don't hesitate to ask if there is anything still unclear!
