Solve the top equation to get on variable on one side
2x-y=6
-y=-2x+6
y=2x-6
then plug in the coordinate for x and y for both equations. if both equations are true then it’s a solution
2=2(2)+6
2=10
4+2=6
so it’s not a solution

Answer:
Isolate.
Step-by-step explanation:
To solve a one-step equation, you must isolate the variable.
For example,
3x = 9.
You must isolate x, which just means you have to get x by itself.
Divide by 3 on both sides to get x by itself.
x = 3.
The answer to this question is isolate.
