Weegy:
One number is eight more than twice another. If their difference is 25, the larger number is 42.
2Y + 8 - Y = 25
Y = 25 - 8 = 17
X = 25 + 17 or X = 2(17) + 8 = 42
User: Solve the following system by graphing.
x + y - 6 = 0
x - y = 0
What is the solution of the system?
User: Solve the following system by graphing.
x - y = 4
x + y = 2
What is the solution of the system?
Weegy: 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)
User: y = 2x + 3
2y = 4x + 6
The system of equations has _____ solution(s).
User: The following system of equations is _____.
y = -1/3x +2/3
2x + 6y = 4
(More) 8
x + y - 6 = 0
x - y = 0
adding up equations the result is: 2x - 6 = 0
2x = 6
x = 6/2 = 3
y = x = 3
The solution for the system x + y - 6 = 0 x - y = 0 is (3, 3)

8
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
there are infinite solutions for the system of equations y = 2x + 3 2y = 4x + 6
