Answer:

The solution is x = 6 and y =1

Explanation :

In the substitution method we solve a system of equation by substituting the value of one variable from an equation to the another equation,

Given system of equations,

x-y = 5 ⇒ y = x - 5.......(1)

2x+y = 13.......(2)

Substitute the value of y from equation (1) to equation (2),

2x+x-5=13

3x-5=13

3x=18

x = 6

Again from equation (1),

y = 6 - 5 = 1
