x+y=5 y=3+x Step 4: Plug back In to find the other variable. x+y=5 (1)+y=5 x=4 Step 5: Check your solution. (1,4) f(1)+(4)=5 (4)=3+(1) The solution is (1,4) . What do you think the answer would be if you graphed the two equations?

If you graph the two equations, you would find that they intersect at the point (1, 4). This is because the system of equations has a unique solution, which is (1, 4). When you plug in x = 1 and y = 4 into both equations, they are satisfied, confirming that this is the correct solution.
