Answer:
Step-by-step explanation:
you know how fractions can be reduces, well, so can equations.
4x - 20y = -16......reduce by dividing by 4
x - 5y = -4
2x - 10y = -8....reduce by dividing by 2
x - 5y = -4
same line......INFINITE SOLUTIONS
or u can do it this way also.....put them in y = mx + b form
4x - 20y = -16
-20y = -4x - 16
y = 1/5x + 4/5......slope is 1/5 and y int is 4/5
2x - 10y = -8
-10y = -2x - 8
y = 1/5x + 4/5.....slope is 1/5 and y int is 4/5
same slope, same y int, means same line with infinite solutions
Answer: infinite number of solutions
Step-by-step explanation:
The second equation is basically doubled the first equation.
4x-20y=-16---------> 4x-20y=-16-------->4x-20y=-16
-2(2x-10y)= -2(-8)----> -4x + 20y=16-->-4x+20y=16
Add down and you get 0=0 or in other words, infinite number of solutions.
