Ineed asap its due tomorrow pleaaasee me 30 points and !

solve each given equation and show your work. tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither.

(a) 20 - 4x = 12 - x + 8 - 3x

(b) 5x + 4x - 3 = 24 + 8x

(c) 5x + 6 = 2x + 6 + 3x - 15

me i beg =(

Step-by-step explanation:

Work: (A)

a) 20−4x=12−x+8−3x

20−4x=12−x+8−3x

20+−4x=12+−x+8+−3x

−4x+20=(−x+−3x)+(12+8)

−4x+20=−4x+20

−4x+20=−4x+20

−4x+20+4x=−4x+20+4x

20=20

20−20=20−20

0=0

In this equation... All real #s are solutions.

Work: (B)

b) 5x+4x−3=24+8x

5x+4x−3=24+8x

5x+4x+−3=24+8x

(5x+4x)+(−3)=8x+24

9x+−3=8x+24

9x−3=8x+24

9x−3−8x=8x+24−8x

x−3=24

x−3+3=24+3

x=27

Work: (C)

c)  5x+6=2x+6+3x−15

5x+6=2x+6+3x−15

5x+6=2x+6+3x+−15

5x+6=(2x+3x)+(6+−15)

5x+6=5x+−9

5x+6=5x−9

5x+6−5x=5x−9−5x

6=−9

6−6=−9−6

0=−15

HOPE THIS HELPS <3 :D

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

dhruv⭐

just needed some points but try socratic
