Answer:
The solution point is (2.5, 5)
Step-by-step explanation:
This is one of the very first steps you need to take in order to solve 2 equations with 2 unknowns. This does not require that you make any adjustments.
2x + y = 10
-2x +2y = 5 Just add. The xs cancel.
3y = 15 Divide by 3
3y/3 = 15/3
y = 5
=========
Now use one of the equations (the top one is easier) to solve for x
2x + y = 10 Substitute y = 5
2x + 5 = 10 Subtract 5
2x +5-5 = 10-5
2x = 5 Divide by 2
x = 2.5
The solution point is (2.5 , 5)
