Question

2. 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) 6x + 4x - 6 = 24 + 9x

(b) 24 - 4x = 15 - 3x + 10 - x

(c) 4x + 8 = 2x + 7 + 2x - 20


Answer:

Answer 1

Answer:Question A only solvable others (B and C)returned as contradiction

Step-by-step explanation:A.

6x+4x-6=24+9x

Group like terms

6x+4x-9x-6=24

10x-9x=24+6

X=30(identity )

B.

Group like terms -3x-x+4x=24-15-10

x-x=24-25

0=-1(contradiction)

C.

Group like terms

4x-2x-2x=7-8-20

0=-21(contradiction)

Answer 2

Answer:

a. neither, one solu

b. contradiction, no solu

c. contradiction, no solu
