Question

Tell whether each equation has no solution, one solution, or infinitely

many solutions.
a. 1+3x = 3x + 1
b. 4x + 1 = 3x + 2
c. 5x + 1 = 5x - 2
d. -3(x+1)=-3x+3
Conving is not permitted.

Answer 1

see below

Explanation:

a. 1+3x = 3x + 1 --> infinite, it's the same thing

b. 4x + 1 = 3x + 2 --> x=1 one solution

c. 5x + 1 = 5x - 2 --> no solution. it's not possible

d. -3(x+1)=-3x+3 --> x=-1, one solution
