One sec
OpenStudy (heart_offire):
im confused on this because there are 2 numbers on top and three on the bottom
OpenStudy (study312):
just add both
OpenStudy (study312):
2 - 9 = -7
2 + 2 = 4, 4 - 15 = -11
-7 ÷ -11 = 0.64
OpenStudy (study312):
so I am actually kinda lost because the top would be -7 unless it wants you to leave the 2x and x2 alone

OpenStudy (study312):
