PLEASE HELP!!!!!!!!!!!!!!!!
Anton [14]

Answer:

<h2>1. subtract 3x, subtract 4, divide by -4</h2><h2 /><h2>2. add x</h2>

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
