Question

what is - 5у - 25 = -40​

Answer 1

Answer:

x=4  

-5y+8x=-18        

linear combination:

cancel out -5y with 5y. combine 8x and 2x

5y+2x=58        

10x. combine -18 and 58 to get 40

10x=40    

40/10=4

So that means..

x=4

Answer 2

Answer:

$\boxed{ \huge{ \bold{ \boxed{ \sf{y = 3}}}}}$

Step-by-step explanation:

$\sf{ - 5y - 25 = - 40}$

Move 25 to right hand side and change it's sign

⇒$\sf{ - 5y = - 40 + 25}$

Calculate

⇒$\sf{ - 5y = - 15}$

Divide both sides of the equation by -5

⇒$\sf{ \frac{ - 5y}{ - 5} = \frac{ - 15}{ - 5} }$

Calculate

⇒$\sf{y = 3}$

Hope I helped!
