3x+7y=5x+2y

complete the missing value in the solution to the equation

(x=-5, y=? )

The missing value in the solution to the equation is -8.

Step-by-step explanation:

Here, the given equation,

-3x+7y = 5x+2y,

if x = -5,

-3(-5)+7y=5(-5)+2y,

15 + 7y = - 25+2y  ( by solving brackets )

15 + 7y + 25 = 2y  ( add 25 both sides )

40 + 7y = 2y

40 = 2y - 7y ( subtract 7 on both sides )

40 =-5y

⇒ y = -8  ( divide both sides by 5 )

Hence, the missing value in the solution to the equation is -8.

i think this could be a possible answer (1 / 84) -1

good luck! : d
