Question

Select all of the equations below that have no solutions.

Select 2 correct answer(s)
3x + 5 = 3x + 8
3(x + 5) = 3x + 15
2(x + 1) = 2x + 1
2x + 1 = 2x + 1

Answer 1

Explanation:

we have to soft the ones that have no solutions.

3x + 5 = 3x + 8

5 = 8

that is never true, and therefore there is no solution.

3(x + 5) = 3x + 15

3x + 15 = 3x + 15

that is always true, and it has therefore infinitely many solutions.

2(x + 1) = 2x + 1

2x + 2 = 2x + 1

2 = 1

this is never true, so, there is no solution.

2x + 1 = 2x + 1

this is always true, so this has infinitely many solutions.

Answer 2

3x + 5 =3x + 8

Explanation:

3x - 3x = 8-5

x = 3
