Question 717033
With not just one but both equations already "solved for y", this system is an ideal candidate for using the Substitution Method. The first equation says the y = 2x. Substituting 2x for the y <i>in the other equation</i> we get:
2x = -x + 3
Now we solve for x. Adding x to each side:
3x = 3
Dividing by 3 we get:
x = 1
Now we use this value for x and either of the original equations to find the y value:
y = 2(1)
So y = 2
The solution is the point (1, 2)
