Question

Solve the system of linear equations.

3x + y = 9y − 2x = 4
A) (1, 6)
B) (−1, 6)
C) (1, −6)
D) (−1, −6)

Answer 1

The answer to your question is: letter A

Explanation:

3x + y = 9

y -2x = 4

3x + y = 9

-1(-2x + y = 4)

3x + y = 9

2x - y = -4

5x = 5

x = 1

y - 2(1) = 4

y = 4 + 2

y = 6

Point (1, 6)
