10. Which point is the solution for this System of equation?

Through substitution, you plug the second equation into the first equation, which would be: 2x + x - 3 = 3. Then combine like terms, which would be: 3x = 6. Divide both sides by 3 to get: x = 2. Now use this x-value in the first equation: 2 (2) + y = 3 ; 4 + y = 3. Now combine like terms, once again, to get y = -1. Therefore the solution to this system of equations is (2,-1) To verify, you will get 3 if you plug in the respective values in to the first equation.
