Answer:
y = -4
x = 3
Step-by-step explanation:
let’s call it 1. x - 2y = 11
Let’s call it 2. 3x - y = 13
___________
lets multiply 2 by 2
(3x - y = 13) 2
this is 3 6x - 2y = 26
___________
Now, let’s substract. 3 from 1
x - 2y = 11
- (6x - 2y = 26)
= -5x = - 15
5x = 15
x = 15/5
x = 3
__________
now, lets solve equation 1 with the value of x.
x - 2y = 11
3 - 2y = 11
- 2y = 11 - 3
-2y = 8
2y = -8
y = -8/2
y = -4
