Answer:

x=.75

Step-by-step explanation:

1 + 3x= -x + 4

1 +3x = 4 - x

  + x        + x

1 + 4x = 4

-1          -1

4x = 3

/4     /4

x = .75

Answer: x = 3/4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x+1=−x+4

Step 2: Add x to both sides.

3x+1+x=−x+4+x

4x+1=4

Step 3: Subtract 1 from both sides.

4x+1−1=4−1

4x=3

Step 4: Divide both sides by 4.

4x 4 = 3 /4

x =  3 /4
