Question

Select steps that could be used to solve the equation 1 + 3x = -x + 4.

Answer 1

For this case we have the following equation:

$1 + 3x = -x + 4$

We must solve the equation by following the steps below:

We subtract 1 from both sides of the equation:

$3x = -x + 4-1$

On the right side of the equation we have that different signs are subtracted and the sign of the major is placed:

$3x = -x + 3$

We add x to both sides of the equation:

$3x + x = 3\\4x = 3$

We divide between 4 on both sides of the equation:

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

Thus, the correct option is option B

Answer:

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

Option B

Answer 2

For this case we have the following equation:

We must solve the equation by following the steps below:

We subtract 1 from both sides of the equation:

On the right side of the equation we have that different signs are subtracted and the sign of the major is placed:

We add x to both sides of the equation:

We divide between 4 on both sides of the equation:

Thus, the correct option is option B
