Question

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

add x, subtract 4, divide by 4
subtract 1, add x, divide by 4
subtract 3x, subtract 4, divide by -4
add x, subtract 1, divide by 4
subtract 3x, subtract 4, divide by 4

Answer 1

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

Answer:

Option B

Answer 2

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
