Question

How many solutions do the equations below have?

5x=5x+3

5x+6=6x+5

5x+6=5x+6

2x+4=4x+2

2x+4=2x+4

2x=2x+4

Answer 1

Answer:

5x = 5x + 3 ; 0 = 3 —> No solution

5x + 6 = 6x + 5 ; 6 = x + 5 ; 1 = x —> One solution

5x + 6 = 5x + 6 —> Infinite many soultion

2x + 4 = 4x + 2 ; 4 = 2x + 2 ; 2 = 2x ; 1 = x —> One soluion

2x + 4 = 2x + 4 —> Infinite many solution

2x = 2x + 4 ; 0 = 4 —> No solution
