Question 561575: Solve the equations by substitution. If the equations are inconsistent and the solution is an empty set, write "no solution".
5x - 2y = 6
x = 5 - y Answer by Edwin McCravy(20060) (Show Source):
You can put this solution on YOUR website! Solve the equations by substitution. If the equations are inconsistent and the solution is an empty set, write "no solution".
5x - 2y = 6
x = 5 - y
The second equation is already solved for x, so
we substitute (5 - y) for x in the first equation:
5x - 2y = 6
5(5 - y) - 2y = 6
25 - 5y - 2y = 6
25 - 7y = 6
-7y = -19
y =
y =
Substitute for y in
x = 5 - y
x = 5 -
x = 5· -
x = -
x =
Solution: (x,y) = (,)
