.2 x + .05 y = .14 (x+y)
and
x+y = 15
Again please NO answers! Only on how to solve.

O.J.=(0.14)(15)=2.1 lit ers.
1. 0.2X+0.05Y=2.1
2. X + Y = 15
To solve by elimination,multiply
both sides of equation 1 by(-)5:
-X-o.25Y=-10.5
X + Y = 15
Y = 6 liters @ 5% O.J.
X = 9 liters @ 20 % O.J.
1. 0.2X+0.05Y=2.1
2. X + Y = 15
To solve by elimination,multiply
both sides of equation 1 by(-)5:
-X-o.25Y=-10.5
X + Y = 15
Y = 6 liters @ 5% O.J.
X = 9 liters @ 20 % O.J.
