4x + 10y = 2
-4x + 8y = 16

Sagot :

32x + 80y = 8y - 4x

36x = -72y

x = -2y

2y = 2

y = 1

x = -2

Answer:

  • One solution

Kind Note:

This question is incomplete. You need to provide the question in order to get the best answer on brainly. In this answer, I will tell you how many solutions are in this system of equations.

Step-by-step explanation:

This question involves the use of 'system of equations'.

  • => 4x + 10y = 2

            -4x + 8y = 16

  • => (4x - 4x) + (10y + 8y) = (2 + 16)
  • => 18y = 18
  • => y = 1 (No further check required)

Since the y-intercept is valid, the system of equations has one solution.

Hence, this system of equations has one solution.
