Question

which value of x makes the open sentence true?

7-x=3x+5

A.x=1.5
B.x=2
C.x=0.5
D.x=3

Answer 1

Is it asking for you to solve for x?

Answer 2

If so, just do inverse operations.

Answer 3

taking like terms, you will have
7-5=3x+x

Answer 4

2=4x

Answer 5

\[\frac{ 2 }{ 4 }=x\]

Answer 6

so, x=0.5

Answer 7

So I would subtract 7 on both sides, so -x=3x-2.
Then, I would subtract 3x on both sides --> -4x = -2.
Make both sides positive by dividing -1 on each side --> 4x = 2.
Divide 4 on each side --> x = 0.5
