Question

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

Answer 1

Answer:

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

B: it has no solution

Step-by-step explanation:

Answer 2

Answer:

1. It has one solution.

2. It has no solution.

Step-by-step explanation:

1.

The given equation is

$3y+4=-2$

Subtract 4 from both the sides.

$3y=-2-4$

Divide both sides by 3.

$y=\frac{-6}{3}$

$y=-2$

Therefore this equation has only one solution.

2.

The given equation is

$5n-4=5n-3$

Subtract both sides by (5n-3).

$5n-4-5n+3=0$

$-1\neq 0$

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