Question

PLEASE HELP
Which ordered pair is the solution to the system of equations? x+y=4 x-y=-6 A. (2, 2) B. (1, −7) C. (−1, 5) D. (−2, 4) @ganeshie8 @hartnn @mathstudent55 @Abhisar @dan815 @iambatman @Callisto @.Sam.

Answer 1

x+y = 4
x - y = - 6

subtract second eq from first
(x+y) -(x-y) = 4-(-6)
2y = 10
y = 5
Put y = 5 in any equation to find value of x

Answer 2

Since you have answers, you could plug in each (x, y) pair to see which makes both equations true. If you want to solve it without plugging in, you would use either elimination or substitution to solve the system

Answer 3

is it b @Miracrown @sangya21

Answer 4

which coordinate have y = 5?

Answer 5

c?
