**Answer:**

x<12

**Step-by-step explanation:**

Let's solve your inequality step-by-step.

x>−3

Step 3: Multiply both sides by 4/(-1).

)*(−3)

x<12

Answer:

x<12

**Answer:**

a. x=-17, y=27

b. x=0, y=-6

c. x=9, y=-1

d. undefined

e. x=4, y=-6

f. x=4, y=0

**Step-by-step explanation:**

a. 3x+y=24

y=3x+24

-x+3x+24=-10

2x=-34

x=-17

-(-17)-y=-10

17-y=-10

-y=-27

y=27

b. 3y=-18

y=-6

-6=-x-6

0=x

c. -2x+17=8-x

9=x

y=8-9

y=-1

d. x-7=x+7

x-14=x

-14=0

e. -4x+10+2x=2

-2=-8

x=4

y=-4(4)+10

y=-16+10

y=-6

f. x+2y=4

x=4-2y

-4(4-2y)-3y=16

-16+8y-3y=16

-16+5y=16

5y=0

y=0

x+2(0)=4

x=4

**Answer: clearly the answer is B hope this helps**
