Certainly! Let's tackle these questions one step at a time.

### Question 1: How can we get Equation [tex]$B$[/tex] from Equation [tex]$A$[/tex]?

Equation [tex]$A$[/tex] is: [tex]\( 2x - 1 + 3x = 0 \)[/tex]

To simplify this, we combine the like terms on the left side of the equation.

- The term [tex]\(2x\)[/tex] is a like-term with [tex]\(3x\)[/tex].
- When we add [tex]\(2x\)[/tex] and [tex]\(3x\)[/tex], we get [tex]\(5x\)[/tex].

So, combining like terms, Equation [tex]$A$[/tex] becomes:
[tex]\[ 5x - 1 = 0 \][/tex]

This new form matches Equation [tex]$B$[/tex]. Therefore, the correct answer to the first question is:

(C) Rewrite one side (or both) by combining like terms

### Question 2: Are the equations equivalent? Do they have the same solution?

Since we derived Equation [tex]$B$[/tex] directly from Equation [tex]$A$[/tex] by combining like terms, both equations should have the same solution.

To confirm, let's solve both equations.

For Equation [tex]$A: Starting from the simplified form derived, which is: \[ 5x - 1 = 0 \] We solve for \(x\): \[ 5x = 1 \] \[ x = \frac{1}{5} \] For Equation $[/tex]B:

Equation [tex]$B$[/tex] is already in the form:
[tex]\[ 5x - 1 = 0 \][/tex]

So solving it follows the same steps:
[tex]\[ 5x = 1 \][/tex]
[tex]\[ x = \frac{1}{5} \][/tex]

Since both equations yield the same solution, they are equivalent. Hence, the correct answer to the second question is:

(A) Yes

In summary:
1. The way to get from Equation [tex]$A$[/tex] to Equation [tex]$B$[/tex] is by combining like terms.
2. Yes, the equations are equivalent and have the same solution.
