Question 438244: Solve and check using the substitution method. x+3y=23 and 3x-2y=3
Answer by robertb(5830) (Show Source): You can put this solution on YOUR website!
From the 1st equation, x = 23 - 3y
==> 3(23 - 3y) - 2y = 3
==> 69 - 9y - 2y = 3
==> 66 = 11y
==> y = 6
==> x = 23 - 3*6 = 23 - 18 = 5.
