The system of equations is coincident. What are the missing values?

4x + 5y = 8

8x + oy = ¨

Answer 1

When 2 lines are coinciding, this means its the same line.
One equation is simply a multiple of the other.

8x = 4x*2
This means the multiplier is 2

5y*2 = 10y

8*2 = 16

The missing values are 10y and 16
