to solve this equation, u need to substitute the first equation, y=2x into the second equation which means that u will replace the y in the second equation to be 2x. after that u just have to solve that equation u have created which will give u the x value. afterwards u have to use the x value that u found to solve for y. so u can use the first or second equation but for this i use the first one becos it is easier to get the y value.
