For this case we have the following equation:
[tex]1 + 3x = -x + 4[/tex]
We must solve the equation by following the steps below:
We subtract 1 from both sides of the equation:
[tex]3x = -x + 4-1[/tex]
On the right side of the equation we have that different signs are subtracted and the sign of the major is placed:
[tex]3x = -x + 3[/tex]
We add x to both sides of the equation:
[tex]3x + x = 3\\4x = 3[/tex]
We divide between 4 on both sides of the equation:
[tex]x = \frac {3} {4}[/tex]
Thus, the correct option is option B
Answer:
[tex]x = \frac {3} {4}[/tex]
Option B
