2X+y=13

y=X-5

Solve using substution

2x + y = 13

y = x - 5

2x + x - 5 = 13

3x - 5 = 13

3x = 18

x = 6

y = x - 5

y = 6 - 5

y = 1

The solution is (6,1)

Y=x-5; 2x+y=13

Solve y=x-5 for y:

Substitute x-5 for y in 2x+y=13:

2x+y=13

2x+x-5=13

3x-5=13 (Simplify both sides of the equation)

3x-5+5=13+5 (Add 5 to both sides)

3x=18

3x/3=18/3 (Divide both sides by 3)

x=6

Substitute 6 for x in y=x-5:

y=x-5

y=6-5

y=1 (Simplify both sides of the equation)
