Question

Which ordered pairs is the solution for the given system.
x + 3y = 10
2x - y = 6
A. (4, 2)
B. (7, 1)
C. (16, -2)
D. (3, 0)

Answer 1

do you prefer substitution or elimination ?

Answer 2

well...substitution is probably easier

x + 3y = 10
x = -3y + 10

now sub -3y + 10 in for x in the other equation and solve for y.
Once you have y, sub that back into either equation and find x.

Answer 3

IS IT c?

Answer 4

let me check...hold on a sec

Answer 5

2x - y = 6
2(-3y + 10) - y = 6
-6y + 20 - y = 6
-7y + 20 = 6
-7y = 6 - 20
-7y = -14
y = 2

x + 3y = 10
x + 3(2) = 10
x + 6 = 10
x = 10 - 6
x = 4

No...answer is A (4,2)
