Answer:
White Gold.
Step-by-step explanation:
This type of gold contains only 75% pure gold, not 100%.
4x=20-8y
x=5-2y now use this value of x in the second equation...
3(5-2y)+6y=15
15-6y+6y=15
15=15 This is true for any y or x value.
So there are infinitely many solutions as the two equations describe the same line.
Sum is the result of adding so
12 + x, but i don't see it as a option.
