You can put this solution on YOUR website! 2x+5y=-2 x=10-8y solve using substitution method need to check my work
----
If you are checking your work, post your solution.
It takes less time to check a solution than to
work thru a substitution.
------------------
2x+5y = -2
x = 10-8y
----
Substitute:
2(10-8y) + 5y = -2
20-16y+5y = -2
20-11y = -2
11y = 22
y = 2
----
Sinc x = 10-8y, x = 10-16 = -6
====================
Note: To check your own answers, substitute
your solution numbers into the original
equations.
