Solve for x. \[\frac{ x-8 }{ 2 }=3\] A.-14 B.7 C.-9 D.2

OpenStudy (aihberkhan):

Okay so the first step is to multiply 2 on both sides.

OpenStudy (aihberkhan):

What do you get? @kweenlexis

pooja195 (pooja195):

Start by multiplying by the reciprocal (the flip of the fraction) Solve for x. \[\frac{ x-8 }{ 2 }=3\] \[(2)\frac{ x-8 }{ 2 }=3(2)\] What do you get?

OpenStudy (aihberkhan):

Oh @pooja195 sorry for taking over. :) You got this :)

OpenStudy (kweenlexis):

8*2 & 2*2 thats what u want me to multiply?

pooja195 (pooja195):

well 2 and 2 cancel out so you are left with x-8=3*2 3 *2=?

OpenStudy (kweenlexis):

3*2=6

pooja195 (pooja195):

x-8=6 next just add 8 to both sides -8+8=? 6+8=?

OpenStudy (kweenlexis):

-8+8=0 6+8=14

pooja195 (pooja195):

Good so x=?

OpenStudy (kweenlexis):

-14????
