Solve the system by the method of elimination.

infinite solutions along the line -3x+y = 6

Step-by-step explanation:

9x -3y = -18

-3x + y = 6

Multiply the second equation by 3

3( -3x+y) = 3*6

-9x +3y = 18

Add this to the first equation

9x -3y = -18

-9x +3y = 18

0 + 0  = 0

This means it is the same line which means there are infinite solutions along the line -3x+y = 6

work is shown and pictured

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
