PLEASE HELP!!!!!!!!!!!!!!!!

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

Choose the answer based on the most efficient method as presented in the lesson.

If the first step in the solution of the equation -x + 6 = 5 - 3x is "subtract 5," then what should the next step be?

add 3x
add x
subtract 6

Answer :

Answer:

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

2. add x

Step-by-step explanation:

1 + 3x = -x + 4.

subtract 3x

1 = -4x + 4

subtract 4

-3 = -4x

divide by -4

(-3)/(-4) = (4x)/(-4)  ⇌ x = 3/4

-x + 6 = 5 - 3x

subtract 5

-x + 1 = - 3x

add x

1 = -2x
