Question

When x = 5, 5y = 2x. Find the value of the expression ((2y+1)-5)+(2×-5-y^2 + 1225)​

Answer 1

Answer: 1211

Step-by-step explanation:

Given :-

x = 5, 5y = 2x

So,

5y = 10, y = 2

Now for the expression :-

(2(2) + 1) -5) + ( 2(-5) - (2)² + 1225)

After solving, we get :-

(2(2) + 1 )-5) + ( 2(-5) - (2)² + 1225)  = 1211
