Question 742514: Please May I have your help on solving this equation?
Use the method of substitution to solve the system of linear equations
2x-y=5
9x-4y=23
The solution is __ (type an ordered pair) Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! 2x-y=5
-Y=-2X+5
Y=2X-5
9x-4y=23 REPLACE Y WITH (-2X-5) & SOLV FOR X
9X-4(2X-5)=23
9X-8X+20=23
X=23-20
X=3 ANS.
Y=2*3-5
Y=6-5
Y=1 ANS.
PROOF:
9*3-4*1=23
27-4=23
23=23
