Question

Five more than a number tripled is half the number. What is the number?
A.
6
B.
–2
C.
–1
D.
1

Answer 1

5 + 3x = (1/2)x solve for x...

Answer 2

I believe it is B. -2
-2x3 = -6 +5 =-1 which is half of -2

Answer 3

5 + 3x = (1/2)x subtract both sides by (1/2)x
-(1/2)x -(1/2)x
5 + 2.5x = 0 subtract both sides by 5
-5 -5
2.5x = -5 then divide both sides by 2.5
/2.5 /2.5
x = - 10/5 = -2 <--

Answer 4

\[3x+5=\frac{ 1 }{ 2 }x\]

subtract 1/2x
\[\frac{ 5 }{ 2 }x+5=0\]

subtract 5
\[\frac{ 5 }{ 2 }x=-5\]

multiply by 2 to get rid of fraction
\[5x=-10\]

divide by 5
\[x=-2\]
