Okay, so basically all you need to do is combine like terms!
in this case, 4y and -3y are like terms... and -1 and 2 are like terms
so, 4y - 3y is 1y or y
and -1 + 2 is 1
so your simplified answer is y + 1
I hope this helps!!
Hmmm I think either D or C
3x + 6 >=0 that's the equation and yes it would be greater
18+0.07x18= 18+1.26 = 19.26
20-19.26= 0.74
So yes she does
