Question

Which system of equations below has infinitely many solutions?

Answer 1

Answer:

The answer is B

Step-by-step explanation:

2x+2y =10 and y= -x +5

These are not in the same form so thats the first step

2x+2y=10

we minus 2x from both side which turns into

2y=-2x+10 (the variable always comes first)

Secon step is to divide 2 from the y to everything so 2y divided by 2 = y

-2 divided by 2 is -x and 2 divided by 10 is 5 and now you have the same equations which leads to infinite

y=-x+5
