Question

Complete the missing value in the solution to the equation. (-5, ) −3x+7y=5x+2y

Answer 1

Step-by-step explanation:

−3x+7y=5x+2y

Put x= -5 in the above equation

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

15 + 7y = -25 + 2y

15+25 = 2y-7y

40= -5y

y= -8

So,the required answer is (-5,-8)

Answer 2

Answer:

The missing value is -7.

Step-by-step explanation:

Here,

x=-5

Then,

−3x+7y=5x+2y

-3×-5+7y= 5×-5+2y

15+7y=-25+2y

7y-2y=-25-15

5y=-35

y=-35/5

y=-7
