You can put this solution on YOUR website!
.08x + .06y = 144
multiply by 100
8x+6y=14400.............1
x + y = 2000............2
8x+6y=14400.............1
1x+1y=2000.............2

multiply (1)by 1
Multiply (2) by -6
8x+6y=14400
-6x-6y=-12000

Add the two equations
2x=2400

/2

x=1200

plug value of x in (1)
8x+6y=14400
9600+6y= 14400
6y=14400 -9600
6y=4800
y=800
