Is (8, -1) a solution of the system, 2x + 3y = 13 and x - y = 9?
A) yes
B) no
**Weegy:** y+4=2x **User:** Is (-2, -5) a solution of the system, 3x + 2y = 4 and 2x - 5y = -29?
A) yes
B) no
**Weegy:** yes **User:** Graph the two equations to solve the system. What is the ordered pair solution?
x + y = 6 and x - y = 4
A) (4, 2)
B) (6, 2)
C) (5, 1)
D) no solution
**Weegy:** What is the solution as an ordered pair?. x = 2y - 2 and 3x - y = 14 we have two equations: x - 2y = -2 and 3x - y = 14 There is equality between both equations, so ... [ ] (More)

No, (-2, -5) is NOT a solution of the system, 3x + 2y = 4 and 2x - 5y = -29.

Plug it in: 3(-2) + 2(-5) = 4, which equals -6 + (-10) = 4, which is already not correct. -16 does not equal -4.

YES, (8, -1) is a solution of the system, 2x + 3y = 13 and x - y = 9.

The answer to x + y = 6 and x - y = 4 is C) (5, 1)

Plug it in: 3(-2) + 2(-5) = 4, which equals -6 + (-10) = 4, which is already not correct. -16 does not equal -4.

YES, (8, -1) is a solution of the system, 2x + 3y = 13 and x - y = 9.

The answer to x + y = 6 and x - y = 4 is C) (5, 1)
