Alright. So, we need to apply the substitution method.
y+5 = x  5
+5
y+5 = x
x = y+5 Now we have our value for x
Plug in the value for x, then solve.
y = 2(y+5) + 1
Distributive property
y = 2*y + 2*5 + 1
y = 2y + 10 + 1
y = 2y + 9
y+2y = 2y + 9
+2y
3y = 9
3y/3 = 9/3
y = 3
Here, we know that y = 3
Now, apply it into an equation to solve for x.
3+5 = x  5
+5
2 = x
Now we know that
x = 2
y = 3
