Question

Tyreese is using algebra tiles to solve the equation below.

Answer 1

for this case we have the following equation:

$2x + 5 = -x + 1$

To resolve:

We add x to both sides of the equation:

$2x + x + 5 = -x + 1 + x$

$3x + 5 = 1$

We subtract 5 on both sides of the equation:

$3x + 5-5 = 1-5\\3x = -4$

We divide between 3 on both sides of the equation:

$x = - \frac {4} {3}$

Answer:

We add x to both sides of the equation

Answer 2

Answer:

The correct option is C) add one positive x-tile to both sides.

Step-by-step explanation:

Consider the provided equation.

2x + 5 = -x + 1

Now to solve the above equation first isolate the variables.

To isolate the variables add x to the both the side of the equation.

2x + 5 + x = -x + 1 + x

Now add the like terms.

3x + 5 =  1

Here we add the x tiles to the both the side of the equation.

Now consider the options.

The correct option is C) add one positive x-tile to both sides.
