Answer 2

Step-by-step explanation:

$\sf\green{5y+10=4y-10}$

⇒$\sf\green{5y-4y=(-10)-10}$

⇒$\sf\pink{y=(-20)}$

.°. y = -20

Let's check it :-

LHS :

$\rm{5y+10}$

→ $\rm{5×(-20)+10}$

→ $\rm{-100+10}$

→ $\rm\blue{-90}$

RHS :

$\rm{4y-10}$

→ $\rm{4×(-20)-10}$

→ $\rm{-80-10}$

→ $\rm\blue{-90}$

.°. LHS = RHS

Hence,y = -20 is the correct solution.
