-7 14 years ago

Answer 1

-7-2<x+2-2<4-2
-9<x<2

Answer 2

ok so since the middle 2 was a pos i added to to the -7 and sub from the ps 4 right?

Answer 3

yes, what we try to do here is to leave the "X" alone, if it has a number added to it, we subtract, if it's divided, we multiply, and apply any operation to the other sides in the inquality

Answer 4

ok so my next on is x+8<3 and x9>-4 so i am thinking my answer is -5<x<5 ?

Answer 5

x+8-8<3-8
x<-5
but what about the second part?

Answer 6

ok you would subtract the -4 from 9 to get x<5

Answer 7

it was written x9>-4, not x+9>-4, x9 means x multiplied by 9

Answer 8

i c thats what confusses me so what do i multiply the x with the 9 or the 9 and 4

Answer 9

for this case, x9>-4, we divide x9 by 9 to get x, and divide the other part of the inequality by 9, so we get x>(-4/9)

PS: we usually write 9x, not x9
