What are the steps for solving 11+n+9+3n<9n-3n-4

12<n

Step-by-step explanation:

11+n+9+3n<9n-3n-4

Combine like terms

20+4n<6n-4

Subtract 4n from each side

20+4n-4n<6n-4n-4

20 < 2n-4

Add 4to each side

20+4 < 2n-4+4

24 < 2n

Divide by 2

12<n

astronomers is your final answer! : )

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
