Find a solution -5x+y=-5 -4x+2y=2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-5x + y = -5, (1)
-4x + 2y = 2. (2)
Apply the Substitution method.
From (1), express y = -5 + 5x and substitute it into equation (2). You will get a single equation for x
-4x + 2*(-5 + 5x) = 2. (3)
Now simplify and solve it:
-4x -10 + 10x = 2,
6x = 2 + 10,
6x = 12.
x =
= 2.
So, you just found the solution x = 2.
Do you know what to do next? How would you find "y"?
