User: x + y = 0 x - y + 2 = 0

User: Solve the following system of equations graphically. y - 4 = 0 2x - y - 2 = 0 What is the solution set?

Weegy: |2x - 5| = 4

2x - 5 = -4 or 2x - 5 = 4

2x - 5 = -4;
2x = -4 + 5;
2x = 1;
x = 1/2;

2x - 5 = 4;
2x = 4 + 5;
2x = 9;
x = 9/2;

x = 1/2 or x = 9/2


User: Given the following system of equations, identify the type of system. x + y = 4 x - y = 6

User: Given the following system of equations, identify the type of system. y = -x + 4 2x + 2y = 8

Weegy: The answer is A.independent.

x + y = 0
x - y + 2 = 0
adding up equations the result is:
2x + 2 = 0
2x = -2
x = -2/2 = -1
y = -x = -(-1) = 1
The solution for the system x + y = 0 x - y + 2 = 0 is (-1, 1)

y - 4 = 0
y = 4;
2x - (4) - 2 = 0
2x = 6
x = 6/2 = 3
the solution for the system y - 4 = 0 2x - y - 2 = 0 is (3, 4)

x + y = 4
x - y = 6
adding up equations the result is 2x = 10
x = 10/2 = 5
5 + y = 4
y = 4 - 5 = -1
the solution for the system x + y = 4 x - y = 6 is (5, -1)

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.
