## anonymous one year ago 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

Is it asking for you to solve for x?

2. iwillrektyou

If so, just do inverse operations.

3. anonymous

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

4. anonymous

2=4x

5. anonymous

$\frac{ 2 }{ 4 }=x$

6. anonymous

so, x=0.5

7. iwillrektyou

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
