Question

How to solve for y if  the equation is y=5/2x + 5 if x is zero

Answer 1

Q,  y=5/2x+x if x is zero 

An, ( y=5/2×0+5 ) as you know if i multiply number to zero you get zero so "x" change to the zero you get
( y=0+5 )= ( y=5 ) that is your answer

Answer 2

$y=\dfrac{5}{2}\cdot0+5\\ y=0+5\\ y=5$
