Question

Which statement describes the system of equations?-5x-4y=-4, 25x+20y=20

Answer 1

Answer:

linear equations in two variable

ax + by + c = 0

hope this helps you

Answer 2

5x-4y equal to -4 ---------eq.1

25x+20y equal to 20 -------eq.2

on multiplying eq.1 by 5

25x-20y equal to -20 -----eq.3

on adding eq.2 and eq.3

50x equal to 0

therefore X equal to 0 divided by 59

therefore X equal to 0
