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

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

Option B

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
