In order to solve the system of equation {x-3y=2 {2x+y=11 using the elimination method which of the following step could be used?

Respuesta :

dannielle
x - 3y =2
2x  + y= 11      | *3

x   - 3 y = 2
6x + 3y = 33
-----------------
7x = 35
x= 35:7
x=5

2x+y=11
2*5 + y = 11
10  + y = 11
y= 11 -10
y= 1
