How many solutions does the following system of equations have
4x-20y=-16
2x-10y=-8

Step-by-step explanation:

you know how fractions can be reduces, well, so can equations.

4x - 20y = -16reduce by dividing by 4

x - 5y = -4

2x - 10y = -8reduce by dividing by 2

x - 5y = -4

same lineINFINITE SOLUTIONS

or u can do it this way alsoput them in y = mx + b form

4x - 20y = -16

-20y = -4x - 16

y = 1/5x + 4/5slope is 1/5 and y int is 4/5

2x - 10y = -8

-10y = -2x - 8

y = 1/5x + 4/5slope is 1/5 and y int is 4/5

same slope, same y int, means same line with infinite solutions
