Please help me
infinitely many solutions occur when one equation is a multiple of the other. Basically they produce they produce the same line in the coordinate plane.
Okay.. so what would I do to find the answer?
an example would be x + y = 6 -2x - 2y = -12 - because the second equation = first multiplied by -2
see if you can find something similar in the 4 given options are the y , x terms and the number in one equation multiplied by the same value to get the other?
Oh okay, I'll look back at them and see. Thank you so much !!
yw Hint - at first it looks like number 2 is the one because 2x* 3 = 6x and 4y * 3 = 12y but 24 *3 does not equal 36 so its not that one.
Yeahh true ... hm. Algebra is my hardest so I dont really know what to do exactly
look at number 3 how do you go from 3x to -9x, and -y to 3y and 14 to -42?
It multiplies by 3 ?
almost - its by -3
so thats the one get it?
So they multiply it by -3 . So that would be the answer?
Yes thank you so much! It's way better to help with the problem instead of just giving the answer... so thank you
if you plotted them on a graph paper thay would be the same line. That is why there are infinite solutions - they are all along this infinitely long line!
yes - you learn something that way.
Oh okay.. now I know this for future references. And yess !
