Answer:
y = 4x; there are an infinite number of solutions
Step-by-step explanation:
Both equations describe the same relation between x and y. The system is "dependent", so has an infinite number of solutions. For any value of x, the solution is ...
(x, y) = (x, 4x)
The answer and equation is 17 - 19 = -2
you just have to move the decimal point 9 places to the right thats an easy trick to remember 1849900000
