Which statement is true about the solutions for the equation 3y + 4 = −2?

it has no solution.
it has one solution.
it has two solutions.
it has infinitely many solutions.

which statement is true for the equation 5n − 4 = 5n − 3?

it has infinitely many solutions.
it has two solutions.
it has one solution.
it has no solution.

A: I think it only has 1 solution because y=-2

B: it has no solution

Step-by-step explanation:

1. It has one solution.

2. It has no solution.

Step-by-step explanation:

1.

The given equation is

Subtract 4 from both the sides.

Divide both sides by 3.

Therefore this equation has only one solution.

2.

The given equation is

Subtract both sides by (5n-3).

LHS is not equal to RHS for any value of n, therefore this equation has no solution.

step-by-step explanation:

the true ones are a b and d
