Question

2. Solve each given equation and show your work. Tell whether each equation has one solution, an infinite number of solutions, or no solution. Explain your answers.

(a)2x+4(x-1)=2+4x
(b)25-x=15-(3x +10)
(c)4x=2x+2x+5(x-x)

Answer 1

A is unsolvable because 4=0.
B can be solved.
C is infinite

Answer 2

A) there are infinite number of solutions because if you replace x with 1 and solve the equation 6 = 6

B) There would be no solutions. Say, x = 1 then if you solve the equation it would be 24=2

C) There would be infinite number of solutions because when you replace x with 1 and sovle the equation you will get 4 = 4
