Question 90370
Hello there,

I recategorised your question so you can get a faster answer. 

1. 4x + 1 + 3 =0

4x = -4

x = -1

Check: -4 + 1 + 3 = 0   


2. square2y+7 + 4=y

I'd like to help you with this but I don't understand what you mean by square2y. Is it the square root of 2y? Please rewrite the question so I can help you.
