SOLVING SYSTEMS OF LINEAR EQUATIONS BY SUBSTITUTION.
Instruction:
Solve each system by the substitution method. First clear all fractions. Check each solution.
(1/4X)-(1/5Y)= 9.........1....PUT Y=5X IN THIS
(1/4X)-(1/25X)=9...MULTIPLY WITH 100X THROUGH OUT
25-4=900X
900X=21
X=21/900=7/300
Y=5X=5*7/300=7/60
CHECK....
(1*300/4*7)-(1*60/5*7)=(1/7)[75-12]=63/7=9.OK
This is the questions?
