What is the result of multiplying the second equation by 2 and adding to the first equation? x+3y=10

2x−y=−1



A. 5x+3y=6

B. 5x+y=8

C. 3x+2y=9

D. 3x−5y=−12

5x + y = 8

Step-by-step explanation:

Given the equations:

x+3y=10 (1)

2x−y=−1 (2)

Multiply (2) by 2

2(2x - y = - 1) = 4x - 2y = - 2

4x - 2y = - 2 - - - (3)

Add (1) and (3)

4x - 2y = - 2

x + 3y = 10

5x + y = 8
