PLEASE I NEED HELP ASAP ITS DUE TOMORROW PLEAAASEE HELP ME 30 POINTS AND BRAINIEST!!!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 - 15PLEASE HELP ME I BEG =(
Accepted Solution
A:
Step-by-step explanation:Work: (A)a) 20β4x=12βx+8β3x
20β4x=12βx+8β3x
20+β4x=12+βx+8+β3x
β4x+20=(βx+β3x)+(12+8)β4x+20=β4x+20
β4x+20=β4x+20
β4x+20+4x=β4x+20+4x
20=20
20β20=20β20
0=0 In this equation... All real #s are solutions.Work: (B)b) 5x+4xβ3=24+8x
5x+4xβ3=24+8x
5x+4x+β3=24+8x
(5x+4x)+(β3)=8x+249x+β3=8x+24
9xβ3=8x+24
9xβ3β8x=8x+24β8x
xβ3=24
xβ3+3=24+3
x=27
Work: (C)c) Β 5x+6=2x+6+3xβ15
5x+6=2x+6+3xβ15
5x+6=2x+6+3x+β15
5x+6=(2x+3x)+(6+β15)5x+6=5x+β9
5x+6=5xβ9
5x+6β5x=5xβ9β5x
6=β9
6β6=β9β6
0=β15HOPE THIS HELPS <3 :D
