Question

-x+y=3, -2x+2y=3

Answer 1

To solve this system of equations, we can use the method of substitution or elimination.

Let's use the method of substitution:

From the first equation, we can express x in terms of y:

x = 3 + y

Now we substitute x in the second equation:

-2(3 + y) + 2y = 3
-6 - 2y + 2y = 3
-6 = 3

This equation is not true, so there is no solution to this system of equations. The two lines represented by the equations are parallel and do not intersect.
