The following system of equations is _____. y = -1/3x + 2/3 2x + 6y = 4
Weegy: The following system of equations is A. independent User: Solve the following system by graphing. x - y = 4 x + y = 2 What is the solution of the system? Weegy: The solution set of (3x - 1)^2 = 5 is x = x = (5^1/2)/3 + 1/3 . (3x - 1)^2 = 5 3x - 1 = 5^1/2 3x = 5^1/2 + 1 x = (5^1/2)/3 + 1/3 User: Solve the following system by graphing. x + y - 6 = 0 x - y = 0 What is the solution of the system? User: y = 2x + 3 2y = 4x + 6 The system of equations has _____ solution(s). User: For the following system, use the second equation to make a substitution for y in the first equation. 2x + y = 6 y = 3x + 4 What is the resulting equation? User: For the following system, use the second equation to make a substitution for y in the first equation. 3x + y = 1 y + 4 = 5x What is the resulting equation? User: For the following system, use the second equation to make a substitution for x in the first equation. x + 5y - 10 = 0 x = 2y - 8 What is the resulting equation in simplest form? (More)

x - y = 4
x + y = 2
adding up equations the result is 2x = 6
x = 6/2 = 3
3 - y = 4
y = 3 - 4 = -1
the solution for the system x - y = 4 x + y = 2 is (3, -1)

y = 2x + 3
2y = 4x + 6
substitute y in the second equation the result is:
2(2x + 3) = 4x + 6
4x + 6 = 4x + 6
4x - 4x = 6 - 6
0 = 0
the system of equations y = 2x + 3 2y = 4x + 6 has infinite solutions.
