Here is a system of equations.

y=2x+5
y=x+3

To solve this system of equations, we can substitute the second equation into the first equation to eliminate the variable "y".

Substituting y=x+3 into the first equation, we get:

x+3=2x+5

Next, we subtract x from both sides of the equation:

3=x+5

Then, we subtract 5 from both sides of the equation:

-2=x

Now, we substitute the value of x back into either of the original equations to solve for y. Using y=x+3:

y=(-2)+3

y=1

Therefore, the solution to the system of equations is x=-2, y=1.
